- A 142g baseball is moving at 17.0 m / s in the + x direction. When hit with a bat by a baseball player, its final velocity is 21.0 m / s in the -x direction. The bat acts on the ball for 6.0 x 10⁻² s. What is the magnitude of the average force exerted by the bat on the ball?A car of mass 1,907 kg collides with a wall. The initial speed of the car is 18.2 m/s. After collision, the car bounced in the opposite direction at a speed of 2.9 m/s. If the collision lasted for 172 ms, what was the average force in newtons exerted on the car by the wall? Express your answer in two decimal places with units of Newton.Male bighorn sheep (120 kg ) engage in head-butting contests to establish dominance. High-speed photography has shown that the impact speed is typically 6.0 m/s and that the collision, which brings both rams to a halt, lasts approximately 0.25 s . Suppose the collision force increases linearly with time until it reaches a maximum Fmax , then decreases linearly to zero at t = 0.25 s. What is Fmax?
