Question

The body is thrown vertically upward and rises to a height of 10 cm. The velocity at which the ball is thrown upward

Answer 1

Answer:

1.4m/s

Explanation:

here h =10cm = 0.1cm

let velocity through which ball is thrown upwards be u

so at highest point its velocity will be 0m/s

so v =o

v²-u²=2gh

-u²= 2×0.l×-9.8m/s

u²=1.96

u=1.4m/s
