Question

car moving with a velocity of 56 km per hour applies brakes and stops in 4 second if the car 800 kg calculate the force applied by the brake and acceleration produced

making space so don't answer :))​

Answer 1

Answer:

V = 56 km\h = 56 X 5\18 = 15.5 m/s

Acceleration = v - u\t

= 0 -15.5 14

= - 15.5 14

= -3.8m\s sq

Mass=800kg =0.8 g

Force = mass X acceleration

= 0.8 X 3.8

= -3.1 N ( ve indicate focre is against motion)

= 3.1 N

Answer 2

Answer:

velocity=56km/h =56×5/18=15.5m/s

acceleration=velocity-u/t

=b-15.514

=-15.514

mass=800g

force=mass×acceleration

=0.8×3.8

=3.1n(vel indicate force is against motion)

=3.1n

i think this is your answer
