Question

Q1. An object is thrown vertically upwards and rises to a height of 10 m. Calculate the velocity
with which the object was thrown upwards? Take g=9.8 m/s?

Answer 1

Answer:

u=14 m/s-¹

Explanation:

Distance travelled, s=10m

speed, v=0

v²=u²+2as

0=u²+2×(-9.8ms-²)×10m

-u²=-2×9•8×10m²/s-²

u=√196ms-¹

u=14m/s-¹
