How much force is needed to accelerate a 66kg skier at 2m/s (squared)? equation: f= 66kg x 2 m/s (squared)=

Aball with a mass of 275 g is dropped from rest, hits the floor and rebounds upward. if the ball hits the floor with a speed of 2.40 m/s and rebounds with a speed of 1.70 m/s, determine the following. (a) magnitude of the change in the ball's momentum (let up be in the positive direction.)

If anyone who can me with this hw? i would really appreciate it

Suppose you plot the distance traveled by an object at various times and you discover that the graph is not a straight line. what does this indicate about the object's acceleration?
