A car of mass 800 kg moving with a velocity of 30 m per second along a horizontal Road id brought to rest by a constant force of 5000 Newton calculate the distance moved by the car before coming to rest

Expert Answer:

retardation produced by the applied force = Force/mass = 5000 / 800 = 6.25 m/s2
 
Distance S moved is calculated using the formula " v2 = u2 - 2×a×S " , with final speed v =0, initial speed u = 30 m/s.
 
S = (30×30)/(2×6.25) = 72 m
