Question

A bowler lifts his bowling ball a distance of 2 meters using 50 joules of energy. If, on Earth, a 1.0 kilograms mass weighs 9.8 Newton's, the mass of the bowling ball used by this bowler is about:​

Answer 1

Answer:e

Explanation:

e

Answer 2

Answer:

m=2.551 kg

Explanation:

Gravitational Potential Energy (GPE)

Energy is the capacity that a body has to do work due to any of its characteristics as speed, height, temperature, and many other physical magnitudes. The GPE is the one that depends on the relative height h that a body of mass m has respect to a given reference, and can be computed as

GPE=m.g.h

The bowler uses 50 Joules of energy to lift the ball by 2 meters, we can know the mass of the ball by solving the above equation for m

$\displaystyle m=\frac{GPE}{g.h}$

$\displaystyle m=\frac{50}{(9.8).(2)}=2.551\ kg$

$\boxed{m=2.551\ kg}$
