a baseball player sprints to the back of the outfield to catch a fly ball. they successfully catch the ball, but don’t have enough time to slow themselves before crashing into the wall. how do the padded walls in the outfield keep players safe.

A 1.1 g pebble is stuck in a tread of a 0.74 m diameter automobile tire, held in place by static friction that can be at most 3.5 N . The car starts from rest and gradually accelerates on a straight road. How fast is the car moving when the pebble flies out of the tire tread?

A. If you catch the ball, with what speed do you and the ball move afterwards?   B. If the ball hits you and bounces off your chest so that afterward it is moving horizontally at 8.25 m/s in the opposite direction, what is your speed after the collision?

A student throws a 120 gram snowball at 7.5 m/s at the side of the schoolhouse, where it hits and sticks. What is the magnitude of the average force on the wall is the duration of the collision is 0.15 seconds?

Problem 3. On a hockey table, pucks A and B of 170 g each impact according to the figure shown. If they collide at 0 and rebound along the indicated trajectories, determine the speed of each puck right after the crash. The discs float due to the air coming out of the table. therefore there is no friction. 57 y 28° X B 30° 40° velocity in 40 m/s to A, 60 m/s to B

The figure(Figure 1) shows a collision between three balls of clay. The three hit simultaneously and stick together. What is the speed of the resulting blob of clay?   What is the direction of the resulting blob of clay?

A collision analyst applies physics principles to reconstruct what happened at automobile crashes. Assume that during a head-on crash between two cars, the cars came to a stop, and a large component of a plastic bumper broke off one car and skidded along the highway shoulder leaving skid marks. What information could the analyst gather from the bumper component and from the skid marks it produced? What measurements would be needed to estimate the speed of the cars just before the collision, and how would they be used?

A hockey puck is sliding on a frictionless ice, in an eastward direction. It collides with a second hockey puck, initially stationary, which then goes off in the Northern direction. What direction is the first hockey puck moving after the collision?

a 3kg red car travelling to the right at 5 m/s strikes a stationary 2kg blue car, locking the two of them together. what is the final velocity of the two cars?
