Question

A rocket of mass 40000kg propelled by a force of 10^6N acquires a speed of 3000m/s determine the power expended

Answer 1

Answer:

3×10⁹ W

Explanation:

Power = work / time

Power = force × distance / time

Power = force × velocity

P = Fv

P = (10⁶ N) (3000 m/s)

P = 3×10⁹ W

Answer 2

We have that a rocket of mass 40000kg propelled by a force of 10^6N acquires a speed of 3000m/s the power expended is

P=3*10^9W

From the question we are told

A rocket of mass 40000kg propelled by a force of 10^6N acquires a speed of 3000m/s determine the power expended

Generally the equation for the Power  is mathematically given as

$P=\frac{work}{Time}$

Therefore

P=Fv

P=10^6*3000m/s

P=3*10^9W

Therefore

A rocket of mass 40000kg propelled by a force of 10^6N acquires a speed of 3000m/s the power expended is

P=3*10^9W
