Question

a car of mass 1800 kg is moving with speed of 10m/s is brought to rest after covering a distance of 50 m calculate the force acting on the car​

Answer 1

Hey mate here is your answer

mass of car=1800kg

initial velocity(u)=10m/s

final velocity (v)=0

distance travelled (s)=50 m

by using v^2-u^2=2as

=0^2-10^2=2×a×50

=0-100=100a

=-100÷100=a

a=-1

force=mass × acceleration

50×-1

force is -50N

Hope it will help you

please mark as brainliest answer

Answer 2

Answer:

180 N

Explanation:

d=u/2a

u=10 m/s

v=0

a=?

50=10/2a

2a=10/50

a=1/5×2

a=1/10

force=mass×acceleration

force=1800× 1/10

=180 N
