Two friends, Barbara and Neil, are out rollerblading. With respect to the ground, Barbara is skating due south at a speed of 3.5 m/s. Neil is in front of her. With respect to the ground, Neil is skating due west at a speed of 3.0 m/s. Find Neil's velocity ((a) magnitude and (b) direction relative to due west, as seen by Barbara.

Expert Solution

Hi,

Hope you are doing well.

PART (a):

Please refer the figure below to understand the concept easier:

From figure,

is Velocity of Neil with respect to ground (m/s).

is Velocity of Barbara with respect to ground (m/s).

We know that, Velocity of Neil with respect to Barbera is given by,

Magnitude of Velocity of Neil with respect to Barbera is given by,

Direction relative to due west is given by,

Where, is the angle between and

due west.

Hope this helped for your studies. Keep learning. Have a good day.

Feel free to clear any doubts at the comment section.

Please don't forget to give a thumbs up.

Thank you. :)

Two friends, Al and Jo, have a combined mass of 166 kg. At the ice skating rink, they stand close together on skates, at rest and facing each other. Using their arms, they push on each other for 1 second and move off in opposite directions. Al moves off with a speed of 5.9 m/sec in one direction and Jo moves off with a speed of 9.7 m/sec in the other. You can assume friction is negligible. 1)What is Al's...

Two friends are playing golf. The first friend hits a golf ball on level ground with an initial speed of 43.5 m/s at an angle of 32.0° above the horizontal . (a) Assuming that the ball lands at the same height from which it was hit, how far away from the golfer, in meters, does it land? Ignore air resistance. (b) The second friend hits his golf ball with the same initial speed as the first, but the initial velocity...

Barbara purchases only two goods, salads, and notepads. Both are normal goods for Barbara. Suppose the price of salad decreases. Barbara’s consumption of notepads will most likely Select one: a. be unchanged as the two goods are not substitutes. b. increase due to the substitution effect. c. decrease since she will spend more of her budget on salads d. increase due to the income effect. ------------------------------------------------------------------------------------------------------------------------------------ 2. There are only two brands of tennis balls Tom purchases: “Wilson” and “Penn.”...

How much higher in energy is this electron with respect to the ground state of H

Part A Suppose an electron is in the n=6 energy level of a H atom. How much higher in energy is this electron with respect to the ground state of H Part B How much additional energy is required to just remove this excited electron from the H atom?

A football is kicked from the ground level at an angle of 55 degrees, with respect to the horizontal. With an initial speed of 15 m/s. What is the horizontal displacement at the end of 3 seconds. And how long does it take the football to reach the highest point in trajectory? What is the approximate magnitude of the vertical component of the final velocity of the football as it reaches the ground? How long is the football in the...

A train with proper length L moves at speed 4c/5 with respect to the ground. A ball is thrown from the back to the front, at speed c/3 with respect to the train. How much time does this take, and what distance does the ball cover, in: (a) The train frame? (b) The ground frame? Solve this by i. Using a velocity-addition argument, as we did in lecture. ii. Using the Lorentz transformations to go from the train frame to...

An M-16 is fired from level ground at an upwards angle of 10 degrees with respect to the horizontal. The initial velocity of the bullet is 948 m/s, but because it is fired at a 10 degree angle, the vertical component of the initial velocity is 165 m/s and the horizontal component is 934 m/s. Ignore air resistance and the curvature of the earth in this problem. (Hint: See the videos Projectile Motion Parts 9-13. For questions 9-14 and 17,...

In an attempt to pull a tree stump out of the ground, a pair of tractors are attached to to stump with ropes. The ground around the stump is muddy, so the force the tractors can exert is somewhat limited. The angle between the ropes is 62.0 ∘. Tractor 1 exerts a force of 850 N and Tractor two exerts a force of 640 N . Part A Find the magnitude of the Resultant (Total) force. As for most vector...
