Question

stone thrown vertically upwards v=20ms^-1..plss find time (g=10ms^2)

Answer 1

Answer:

here in this question

u=20m/s^1

a=-10m/s^2

v=0m/s (as object is going up)

now using the first equation of motion

v = u + at

0 = 20 + -10*t

-20 = -10t

t=2s

hence time during this upward motion would be 2 s
