Question

Question 8 An automobile vehicle has a mass of 1500 kg. What must be the force between the vehicle and road if the vehicle is to be stopped with a negative acceleration of 1.7 m s −2 ?
Class 9 - Science - Force and Laws of Motion Page 128

Answer 1

1500*(-1.7)= -2550N negative sign shows force is acted in opposite direction

Answer 2

☺ Hello mate__ ❤

◾◾here is your answer...

m = 1500 kg

v = 0 m/s

a = –1.7 ms–2( retardation)

From Newton's second law of motion:

Force = Mass × Acceleration

= 1500 × (–1.7)

= –2550 N

Hence, the force between the automobile and the road is –2550 N, in the direction opposite to the motion of the automobile.

I hope, this will help you.

Thank you______❤
