A baseball with a mass of 141 g is thrown horizontally with a speed of 40.1 m/s (90 mi/h) at a bat. The ball is in contact with the bat for 1.05 ms and then travels straight back at a speed of 45.2 m/s (101 mi/h). Determine the average force exerted on the ball by the bat. Neglect the weight of the ball (it is much smaller than the force of the bat) and choose the direction of the incoming...

STEP 1 Force: Just after releasing the block, calculate the force exerted on the block by the spring, the force exerted on the block by the Earth, and the net force: spring,r# 2.64 Earthy-6769 net.y - 1.96 0.676N 1.96 N Momentum update: Just after releasing the block, the momentum of the block is zero. Approximate the average net force during the next timel by the force you just calculated. At t0.07 seconds, what will the new momentum and velocity of...

A spring has a relaxed length of 36 cm (0.36 m) and its spring stiffness is 9 N/m. You glue a 83 gram block (0.083 kg) to the top of the spring, and push the block down, compressing the spring so its total length is 19 cm. You make sure the block is at rest, then at time t = 0 you quickly move your hand away、The block begins to move upward, because the upward forc.e on th€ block by...

please help!
The figure below shows a metal ball with a mass of 2.84 kg bouncing off a wall. The ball has the same speed just before and just after the impact (v - 10.0 ms, and the angle its path makes with the wall is 8 - 60.0° as shown. (Because we are analyzing the motion of the ball over a very short time just before and after Impact, you may safely ignore the effect of gravity on the...
