Question

An object of mass 5 kg is moving
with a velocity of 10 m/s. A force
is applied so that in 20s,
it
allains a velocity of 25 ms
what is the force applied a
on
the object​

Answer 1

Answer:

F = 3.5 kg m/sec2

F = 3.5 N

Explanation:

m=5kg

v=10m/s

t=20s

u=25m/s

force F = m* (u-v)/t

= 5 * (25-10)/20 kg m/sec2

= 5* 15/20 kg m/sec2

= 3.5 N
