An object of mass 1 kg is falling from the height h = 10 m. Calculate
What will be the speed of the object when it hits the ground?
(Assume g = 10 `ms^(-2)`)

Text Solution

Verified by Experts

When the object is just about to hit the ground, the total energy is completely kinetic and the potential energy, U = 0.
`E=KE=1/2mv^(2)=100J`
`v=sqrt(2/mKE)=sqrt(2/1 times 100)=sqrt(200)=14.12ms^(-1)`
