Question

an object is thrown vertically upward and Rises to a height of 10 M calculate the velocity with which the object was thrown upwards

Answer 1

Distance travelled, s 10m

Final velocity, v 0m/s

Acceleration due to gravity ,g 9.8

Acceleration of the object ,a -9.8

1) v square = u square +2as

0 square=u square +2×-9.8×10m

u square= -2×9.8×10

u= √196

u=14

2) v= u+at

0=14+(-9.8)×t

t= 1.43s
