In order to measure the speed of an arrow with mass of 100 g, you shoot it into a block of putty with mass of 3 kg that is suspended by a 2 m long string hanging from the branch of a tree. The arrow gets stuck in the block of putty, which then swings back reaching a maximum height of 13 cm above the original position.

a) What is the speed of the putty and arrow right after the arrow gets stuck in the putty?

b) How much kinetic energy do the putty and arrow have then?

c) How large is the gravitational potential energy of the arrow and putty when they reach the maximum height?

d) How large is the kinetic energy of the arrow before it hits the putty?

e) What is the initial speed of the arrow?

f) How much kinetic energy is lost in the collision of the arrow with the putty?

You shoot an arrow into the air at an initial velocity of 12.5m/s at an angle of 40º. Find the maximum height the arrow reaches in the air. Find the time it takes to reach its maximum height. Find the time it takes to hit the ground. Assume its flight in the air is symmetrical, with the first half of flight traveling upward, and the 2nd half of flight traveling downward. Find how far away it hits the ground.

A 60 kg archer, standing on frictionless ice, shoots a 120 g arrow at a speed of 95 m/s. a) Does the bow exert a constant force or a variable force on the arrow? b) Is this situation considered an isolated system or a non-isolated system? What other forces would you include in a free-body diagram? Would these other forces contribute to the velocity of either the arrow or the archer? c) What pair of forces exist that causes the...

A bullet of mass 148 g and a speed v impacts on a pendulum of mass 6.18 kg and length 200 cm. The bullet embeds itself in the pendulum bob. The pendulum then travels in a complete and perfect circle. (a) If the pendulum is suspended by a light, stiff rod, what is the minimum speed of the bullet? (b) If the pendulum is suspended by a string, what is the minimum speed of the bullet?

William Tell shoots an apple from his son's head. The speed of the 118-g arrow just before it strikes the apple is 20 m/s, and at the time of impact it is traveling horizontally. If the arrow sticks in the apple and the arrow/apple combination strikes the ground 7.7 m behind the son's feet, how massive was the apple? Assume the son is 1.85 m tall.

A toy car with a mass of 120 g moves to the right with a speed of 0.64 m/s. A small child drops a 36.0-g piece of clay onto the car. The clay sticks to the car and the car continues to the right. What is the change in speed of the car? Consider the frictional force between the car and the ground to be negligible.

If 17.5 g of NaCl is dissolved in 100. g of water, what is the mass...

If 17.5 g of NaCl is dissolved in 100. g of water, what is the mass % concentration of NaCl in this solution? Note: 1. Use 3 sig figs for your final answer. 2. Do not answer as fractions. For example, if you think 30% is the correct answer, either "30" or "30%" will be accepted, but "0.30" will not. "30%" will actually be converted to 30 automatically
