Question

If a body is thrown vertically upward and it travels 980 m round the trip, calculate the speed with which it was thrown up.​

Answer 1

ANSWER

Here, we have to use equation of motion

Here, we taken upward direction as +ve y axis

s : distance travelled

u : initial velocity

t : time

s=ut−21gt2 

s=60×7−21×10×72=420−245=175 m
