As we know the formula of kinetic energy is
here given that
KE = 150,000 J
mass = 120 kg
we can use this to find speed
So speed of above object is 50 m/s

Answer:
50 W
Explanation:
<h3><u>Given :</u></h3>- Force applied = 100 N
- Distance covered = 5 metres
- Time = 10 seconds
Power
<h3><u>Solution :</u></h3>For calculating power, we first need to know about the work done.
Now, substituting values in the above formula;
Work = 100 × 5
= 500 Nm or 500 J
We know that,
Substituting values in above formula;
Power = 500/ 10
= 50 Nm/s or 50 W
Hence, power = 50 W .
