Question

A particle is thrown vertically up with initial speed
30 m/s. Taking acceleration due to gravity as
10 m/s, the total time of flight of the particle is​

Answer 1

Answer:3 seconds

Explanation:

Newton's first law of motion says that v=u+gt

Where v=initial velocity=0

U=final velocity=30m/s

g=acceleration due to gravity=10m/s

t=time
