Question

A discus thrower throws a 1.6kg discus at 25m/s what's the kinetic energy?​

Answer 1

Answer:

500 J

Explanation:

The kinetic energy of an object can be found by using the formula

$k = \frac{1}{2} m {v}^{2}$

where

m is the mass

v is the velocity

From the question

m = 1.6 kg

v = 25 m/s

We have

$k = \frac{1}{2} \times 1.6 \times {25}^{2} \\ = 0.8 \times 625 \\ = 500$

We have the final answer as

500 J

Hope this helps you
