The force exerted by the footballer on football in the given time interval is 5N.
Given:
Linear momentum, p = 3 kgm/s
Time interval, t = 0.6 seconds
To Find:
The force exerted by the footballer on football in the given time interval.
Solution:
We are required to find the force exerted by the footballer on football in the given time interval.
The force and momentum relation is given as
Force, F = p/t ------(1)
where p = 3 kgm/s and t = 0.6sec
On substituting the values of p and t in equation(1)
F = 3/0.6
F = 5 N
Therefore, The force exerted by the footballer on football in the given time interval is 5N.
