A force acts on a body of mass 200g.the velocity of the body changes from 15m/s to 25m/s in 2.5s.what is magnitude of the force, assuming the force to be constant?

Given:
m=200g
=200 into 10^-3 kg
=0.2 kg
u=15m/s
v=25m/s
t=2.5s
According to the given data we can impliy the formula for Force as:
F=ma,,,,,,,,,,,
but here we don't know acceleration.So,,,
a=v-u/t
=25-15/2.5
=10/2.5
=4
Now we can substitute acceleration in force formula:
F=ma
=0.2 into 4
=0.8 N

Answer:

=0.8 N

Explanation:

Given:

m=200g

=200 into 10^-3 kg

=0.2 kg

u=15m/s

v=25m/s

t=2.5s

According to the given data we can impliy the formula for Force as:

F=ma,,,,,,,,,,,

but here we don't know acceleration.So,,,

a=v-u/t

=25-15/2.5

=10/2.5

=4

Now we can substitute acceleration in force formula:

F=ma

=0.2 into 4

=0.8 N
