An object takes 5 s to reach the ground from a height of 5 m on a plant. What is the value of g on the plant ?

Text Solution

Verified by Experts

Data : `u=0m//s, s= 5m, t=5s, g= ?`
`therefore s=(1)/(2)g t^(2)`
`therefore 5m=(1)/(2)gxx(5s)^(2)=(1)/(2)gxx5sxx5s`
`therefore g=(2)/(5)m//s^(2)=0.4m//s^(2)" (on the planet)."`
