If a 5 kg object was raised to a height of 10 m during 3 seconds. What is the power?

Sagot :

Lanuel

Answer:

A. Energy = 490 Joules

B. Power = 16.3 Watts

Explanation:

Given the following data;

Mass = 5kg

Height = 10m

Time = 3 seconds

To find the power;

First of all, we would have to determine the energy possessed by the object due to its height (potential energy).

We know that acceleration due to gravity is equal to 9.8m/s²

Energy = mgh

Energy = 5*9.8*10

Energy = 490 Joules

Now, we would find the power;

Power = energy/time

Power = 490/3

Power = 16.3 Watts
