Question

What is the mass of a base ball that has a kinetic energy of 100 I and is teravelling at 5 m per second
​

Answer 1

Explanation:

the mass of the bass boll that has a kinetic energy of 100j and speed of 5 m/s is 8 kg

Answer 2

Answer:

Mass = 8 kg

Explanation:

Given that:

Kinetic Energy, K.E = 100 J

Velocity, v = 5 m/s

To find: Mass

The equation for K.E is,

$K.E = \frac{1}{2} mv^{2}$

Substituting the values, we get,

$100 = \frac{1}{2} * m * 5^{2}$

$100 = \frac{25m}{2}$

$25m = 100 * 2$

$25m = 200$

$m = \frac{200}{25}$

$m=8$
