A train travels with a constant speed of 20.0m/s for 7.00s. Determine all

1 answer:

8 0

Answer:

acceleration is zero m/s²

Explanation:

It is given that the train travels at constant speed (i.e speed does not change)

If speed does not change, then the train is neither accelerating or decelerating (i.e acceleration is zero)

105 kg m/s

Explanation:

The change in momentum of the car is equal to the impulse, which is equal to the product between the force applied and the time of the collision:

$\Delta p= F \Delta t$

in this case, the force applied is F=60.0 N, while the time of the collision is $\Delta t=1.75 s$ , so the change in momentum of the car is

$\Delta p=(60.0 N)(1.75 s)=105 kg m/s$
