Question

. A body of mass 45 kg, is moving with a constant velocity of 10
m/sec. A constant force acts on the body for four seconds, and the
speed of the body becomes 2m/sec. in opposite direction. Calculate the
acceleration produced.​

Answer 1

Answer:-3m/s2

Explanation:mass-45kg

U=10m/s

T=4seconds

V=-2mls

As the force is constant so acceleration will also be constant

V=u+at

-2=10+a4

a= -3 mpersecondsquare
