A stone thrown upwards from ground level...

A stone thrown upwards from ground level, has its equation of height `h=490t-4.9t^(2)`where`'h'` is in metres and `t` is in seconds respectively. What is the maximum height reached by it ?

Text Solution

Verified by Experts

The correct Answer is:
`12250m`
`(ds)/(dt)=490-9.8t=0, t=(490)/(9.8)=50 s ec o nd`
`S_(max)=490xx50-4.9xx2500=12250m`
