G A bat hits a moving baseball. If the bat delivers a net eastward impulse of 1.0 N-s and the ball starts with an initial horizontal velocity of 3.8 m/s to the west and leaves with a 5.7 m/s velocity to the east, what is the mass of the ball (in grams)

105 g

Explanation:

We are given that

Impulse=I=1 N-s

Initial velocity,u=-3.8 m/s

Final velocity,v=5.7 m/s

We have to find the mass of the ball.

Impulse=Change in momentum

I=m(v-u)

Using the formula

Where 1 kg=1000 g

answer: point c: b. 1/2 potential, 1/2 kinetic, point a: 3/4 of its potential energy, point d or b: 3/4 potential, 1/4 kinetic

explanation: i cant explain. it's difficult to explain.

i'm just gonna leave this comment here, so i can get a challange done-
