Answer:
12.5 N is the force exerted by the object.
Explanation:
Given:-
- u = 0m/s
- v = 10m/s
- t = 4 sec
To find:-
The force exerted by the object
Solution:-
First we need to calculate the acceleration, as it's not given.
a = v-u/t
a = 10-0/4
a = 10/4
a = 5/2
a = 2.5m/s²
F = m•a
F = m× a
F = 5 × 2.5
F = 12.5 kg m/s²
F = 12.5 N
Therefore the force exerted is 12.5 N.
