Jasmine is running away from a monster with a speed of `5 m s^(-1)` . If her weight is 100N , then find out the energy spent by Jasmine to escape the monster.
(Take g = `10 m s^(-2)` , energy possessed by a body in motion = 1/2 `mv^(2)` where m = mass of the body , v = velocity)

Answer

125 J

Explanation

`V = 5 ms^(-1)`
W = mg = 100 N
m = 10 kg
Kinetic energy = 1/2 `mv^(2)`
`= 1//2 xx 10 xx (5)^(2)`
= 125 J
