Question

. An object of mass 10 kg is thrown vertically upwards with the velocity of 20 m/s. Find the maximum height reach the object (g = 10 m/s2) *
a)20m
b) 5m
c) 10m
d) 40m​

Answer 1

Answer:

20m

Explanation:

Here u=20m/s

v=0m/s

v²=u²+2gh

0=(20m/s)² +2x10m/s²xh

20m/s²xh=400m²/s²

h=400m²/s²/20s²/m

h=20m
