Question

1500 kg Peugeot car is traveling at 16.67 m s ⁻¹ and accelerates to 30.56 m s ⁻¹ for 2 minutes. Calculate the impulse of the car.​

Answer 1

2084 kg*m/s

Step-by-step explanation:

Impulse is change in momentum

Mathematically;

Impulse, J= F*t=mΔv where

F= ma = 1500 * { 30.56 - 16.67}/2*60

F= 1500 *0.11575

F= 174 N

J=F*t

J= 174*120*0.1

J= 2084 kg*m/s
