Question

Find the acceleration of a 600 kg car that experiences an impulse of 18,000 kgm/s in 0.05 seconds.

I need help with this question, i don’t understand it

Answer 1

600m/s²

Step-by-step explanation:

Given parameters:

Mass of car = 600kg

Impulse = 18000kgm/s

Time = 0.05s

Unknown:

Acceleration = ?

Solution:

To solve this problem, let us find the force that cause the impact first;

Impulse = Force x time

Force =
`(impulse)/(time)` =
`(18000)/(0.05)` = 360000N

So;

Force = mass x acceleration

Acceleration =
`(Force )/(mass)` =
`(360000)/(600)`

Acceleration = 600m/s²
