Question

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

Answer 1

20 m/s.

Step-by-step explanation:

Mass of body m: 10kg

The kinetic energy of the body is given as;
`K.E= (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=(√(2K*E) )/(m)`
`V= (√(2*2000) )/(10)` =
`V=20m/s`

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

20 m/s.
