The momentum, final momentum, change in momentum and force experience by a 1500 kg racing car travelling at 30 m/s are:
A. The momentum of the car is 45000 Kgm/s
B. The final momentum of the car is 0 Kgm/s
C. The change in the momentum of the car is –45000 Kgm/s
D. The force experienced by the car is –9000 N
Momentum is simply defined as the product of mass and velocity i.e
<h3>Momentum = mass × velocity </h3>
A. Determination of the momentum of the car.
Mass = 1500 Kg
Velocity = 30 m/s
<h3>Momentum =? </h3>
Momentum = mass × velocity
Momentum = 1500 × 30
<h3>Momentum = 45000 Kgm/s</h3>
Thus, the momentum of the car is 45000 Kgm/s
B. Determination of the final momentum of the car
Mass = 1500 Kg
Final Velocity = 0 m/s
<h3>Final Momentum =?</h3>
Final momentum = mass × Final velocity
Final momentum = 1500 × 0
<h3>Final momentum = 0 Kgm/s</h3>
Thus, the final momentum of the car is 0 Kgm/s.
C. Determination of the change in the momentum of the car
Initial momentum = 45000 Kgm/s
Final momentum = 0 Kgm/s
<h3>Change in momentum =?</h3>
Change in momentum = Final momentum – Initial momentum
Change in momentum = 0 – 45000
<h3>Change in momentum = –45000 Kgm/s</h3>
Thus, the change in the momentum of the car is –45000 Kgm/s
D. Determination of the force experienced by the car.
Change in momentum = –45000 Kgm/s
Time = 5 s
<h3>Force =? </h3>
Force = change in momentum / time
Force = –45000 / 5
<h3>Force = –9000 N</h3>
Thus, the force experienced by the car is –9000 N
