Question

The kinetic energy of a 10-kilogram object is 2000 joules. What is the speed of the object, in m/s?

Answer 1

Answer:

20 m/s.

Explanation:

Mass of body m: 10kg

The kinetic energy of the body is given as; $K.E= \frac{1}{2} * m * v^{2}$

Value of Kinetic energy K.E = 2000 Joules

V is the body's velocity, and M is the body's mass.

Calculating the value of velocity; $V=\frac{\sqrt{2K*E} }{m}$  $V= \frac{\sqrt{2*2000} }{10}$  = $V=20m/s$

Velocity maintained by the body having a kinetic energy of 2000J is

20 m/s.
