In watching the examples of momentum by the student, he later used a 4.1 kg bowling ball to hit the pens about 3.5 seconds after he released the ball. By knowing that a bowling lane is 18.3 meters long you can calculate the momentum that the bowling ball hit the first pen with to be *

Momentum = 21.44 N.s

Explanation:

First we need to find the speed of the ball by using following equation. Assuming the speed of ball to be constant:

where,

v = speed of ball = ?

s = distance covered by ball = 18.3 m

t = time taken = 3.5 s

Therefore,

Now, the momentum of ball will be:

Momentum = 21.44 N.s

what was the acceleration of the 2 kg cart?

⇒ 16.0 cm/s2

what was the acceleration of the 4 kg cart?

⇒ 8.1 cm/s2

what was the acceleration of the 6 kg cart?

⇒ 5.3 cm/s2

i believe the answer is a hope it and is correct
