Question

If a 2,000-kg car hits a tree with 500 n of force over a time of 0.5 seconds, what is the magnitude of its impulse?

Answer 1

Impulse = Force * time
Impulse = 500N *0.5 s =250 N*s

Answer 2

Answer:

The magnitude of its impulse is 250 N-sec.

Explanation:

Given that,

Mass of car = 2000 kg

Force = 500 N

Time = 0.5 sec

We need to calculate the impulse

Using formula of impulse

$I = F\times\delta t$

Where, F = force

$\Delta t$ = time

Put the value into the formula

$I=500\times0.5$

$I=250\ N-s$

Hence, The magnitude of its impulse is 250 N-sec.
