Question 3

Initial kinetic energy = (1/2)*m*vi²

Final kinetic energy = 0

Work done to dissolve this kinetic energy = F*d

Let

(1/2)*m*vi² = F*d

m is the mass given 41 Kg
vi is the initial velocity 53 Km/hr ( Convert it to m/s )
F is the force needed in this question
d is the distance moved by the car 65 cm ( Convert it to m )
