A hiker stands on the edge of a cliff 490 m above the ground and throws a stone horizontally with an initial speed of `15ms^(-1)` Neglecting air resistance, find the time taken by the stone to reach the ground and the speed with which it hits the ground? `(g=9.8ms^(-2))`

Text Solution

Verified by Experts

time =10 seconds
`V=sqrt(V_(s)^(2)+V_(y)^(2))=sqrt(15^(2)+98^(2))=99.1ms^(-1)`
