Question

a vehicle of mass 120kg is moving with a uniform velocity of 180km/h. the force required to stop the vehicle in 10s is​

Answer 1

Explanation:

F=M*A

A=0-180/10

= -180/10

= -18

So, F=M*A

F=120*-18

F=-2160

Here - sign represents that force is in opposite direction

Answer 2

Explanation:

Answer:-

u= 108km/h^2 , m= 120kg

t= 10sec

v =a,

v= u + at

u= -a × (10/3600)

a= -30/10ms^-2

= -3ms^2

=F=ma

=120× 3

=360N

ANSWER IS 360N.
