A ball of soft clay with mass 1 kg falls from a height of 10 m starting at rest. When the clay hits the ground it flattens and comes to a stop. Which of the following is true? Gravity does work on the ball equal to 980 J, and all this energy is dissipated during the deformation of the ball on impact. Gravity does work on the ball equal to 98 J, and all of this energy is dissipated during...

A ball of mass 0.320 kg that is moving with a speed of 5.7 m/s collides head-on and elastically with another ball initially at rest. Immediately after the collision, the incoming ball bounces backward with a speed of 3.4 m/s . Calculate the velocity of the target ball after the collision. Calculate the mass of the target ball.

A small ball has a mass m = 4.0 x 10^-8 kg and a charge of q = -2.0 x 10^-5 C. It enters a box with an initial speed of v0 = 1.0 x 10^4 m/s. The point where the charge leaves the box has an electrical potential 350 x 10^3 higher than the entry point. (a) Find the speed of the ball as it leaves the box. (b) Suppose that the charge on the ball were q =...

5. Ball 1 has a mass of 2.0 kg and is suspended with a 3.0 m rope from a post so that the ball is stationary. Ball 2 has a mass of 4.0 kg and is tied to another rope. The second rope also measures 3.0 m but is held at a 60.0° angle, as shown in Figure 7. When ball 2 is released, it collides, head-on, with ball I in an elastic collision. (a) Calculate the speed of each...

A 10 kg mass slides on a frictionless surface with speed 10 m/s, and has an elastic collision with a 2.0 kg mass. Assume both masses remain along a straight line before and after the collision. (a) If the 10 kg mass is at rest after the collision, what was the initial velocity of the 2.0 kg mass? What was the final velocity of the 2.0 kg mass? (b) If the 2.0 kg mass is at rest after the collision,...
