A0.15 kg baseball is hit by a baseball bat. right before it is hit, the ball’s speed is 30 m/s, and right after it is hit, the ball’s speed is 50 m/s in the opposite direction. what is the magnitude of the net impulse that is applied to the ball?
10.5 kg? m/sa. 4.5 kg? m/sb. 12.0 kg? m/sc. 7.5 kg? m/sd. 3.0 kg? m/s

Impulse will be 12 kgm/sec

So option (b) will be correct option

Explanation:

We have given mass of the baseball m = 0.15 kg

Ball speed before hit

Ball speed after hitting   ( negative direction due to opposite direction )

We have to find the impulse

We know that impulse is equal; to the change in momentum

So change in momentum =

So option (b) will be correct option

i think it’s a. this is because if they measured the mass of something with a mass of 150g, then their final answer would have to be approximately 150g. though all of their answers are almost 150, rosa and tran have the closest answers (or the exact answer) to the accurate one.
