Question

A car weighing 1600 kg is accelerated to 30 m/s in 20 seconds calculate its
Initial velocity
Final velocity
Magnitude of force applied
Acceleration of car

Answer 1

Answer:mu= 1600×30=48000

mv=1600×0=0

change in momentum=mv-mu=0-48000÷20=-2400

acceleration=-1.5

force=ma=1600×(-1.5)=2400N

Answer 2

Answer:

u = 0 m/s

v = 30 m/s

a = (v - u)/t = 30/20 = 1.5 m/s^2

m = 1600 kg

F = ma = 1600 * 1.5 = 2400 N
