What is the impulse that a car with mass of 5kg experiences when its velocity changes from -9m/s to 25m/s?

!

170 kg m/s

Explanation:

Impulse = change in momentum

J = m Δv

J = (5 kg) (25 m/s − (-9 m/s))

J = 170 kg m/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
