Question 1-

In a bizarre way to test the speed of a clay ball shot from a slingshot, a wooden block is set up outside the lab on the concrete. The sticky clay ball has a mass of 10.0 g and is hurled perfectly horizontally by a man with his slingshot at a 90 g wooden block initially at rest on the concrete, a compete horizontal surface. The clay sticks to the block. After impact, the block slides 7.50 m before coming to rest. If the coefficient of friction between block and surface is 0.650, what was the speed of the clay (in m/s) immediately before impact?

m/s

Question 2-

In the sport of speed skating, the top athletes experience centripetal acceleration of approximately 0.65 g (meaning the centripetal force is about 65% of their weight). If the radius of the inner lane is about 22.6 meters, how fast are the skaters going?

m/s

Question 56) PART 1) In the figure an electron is shot at an initial speed of v0 = 4.62 × 106 m/s, at angle θ0 = 40.9 ˚ from an x axis. It moves through a uniform electric field = (5.40 N/C). A screen for detecting electrons is positioned parallel to the y axis, at distance x = 1.84 m. What is the y component of the electron's velocity (sign included) when the electron hits the screen? PART 2) In...

A ball of clay with a mass of 4.0 kg, starting from rest, falls from a height of 0.20 m above a block with mass 1.0 kg that rests on top of a spring with spring constant 90 N/m. The block then sticks to the block and the system undergoes simple harmonic motion. Please submit your answers to the following questions on a separate sheet of paper (or multiple sheets of paper). i. Write the formulas for the position, velocity,...

Assume that the speed of the ball is what you found the in previous question. What is the tension force in the rope when the ball is the bottom of its circular path? Enter you answer in multiples of (mg). For example, if you find the tension force is you should enter 3.75 as you answer. My speed was 3.13 m/s - marked correct. the Radius is 1m. The answer is not 1.32 - as previously answered on another question.
