Answer:
The power will be "250 watt". A further explanation is given below.
Step-by-step explanation:
The given values are:
Force,
F = 50 N
Displacement,
d = 20 m
Time,
t = 2.0 seconds
Whenever the block is pulled, the angle will be "0" i.e., Cos0° = 1
Now,
The work will be:
=

On substituting the given values, we get
=

=

=

Now,
The Power will be:
=
