Question

Suppose that a bowling ball is lifted 1.5 m so that its gravitational potential energy is 90 J. How much does the bowling ball weigh?​

Answer 1

Answer:

the weigh of bowling will be 2.3

Answer 2

Given: A bowling ball is given.

h = 1.5 m

P. E. = 90 J = 90 kg $m^{2}$/$s^{2}$

g = 9.8 ~ ≅ 10 m/s2$s^{2}$

To find: m = ?

Step-by-step Solution:

Potential Energy formula is

$U= m\:g\:h$

$m=\frac{U}{gh}$

$m = \frac{90}{10 \times 1.5}$

$m = 6 \: kg$

Thus, the bowling ball weighs 6 kg.
