In order to catch a ball, a baseball player moves his hand backward in the direction of the ball's motion. Doing this reduces the force of impact on the player's hand principally because it:. a. decreases the impulse on the glove.
b. decreases the change in momentum of the ball.
c. increases the impact time
d. increaes the impulse on the gove

i don’t know what the answer is i wish i

what is the speed of a softball that travels 20m in 2secs

speed = 20/2 = 10 m/s

the chart show the masses and velocities of two colliding objects that stick together after a collision.

according to the law of conservation of momentum, the momentum of the object after the collision is  

answer

1,500

kg • m/s.

d. platinum would have the greatest temperature increase because it has the lowest specific heat.
