Question

49. A 6.1-kg bowling ball is liſted 2.1 m to a shell. Find

the increase in the ball-Farth system's energy.

Answer 1

125.5J

Step-by-step explanation:

Given parameters:

Mass of the bowling ball = 6.1kg

Height of lifting = 2.1m

Unknown:

Increase in the ball energy = ?

Solution:

The ball has changed position by moving it from one point to another. So, it has acquired more potential energy.

Potential energy = mgh

m is the mass

g is the gravity

h is the height

Now insert the given parameters and solve;

Potential energy = 6.1 x 9.8 x 2.1 = 125.5J
