Question

a stone is falling from the mountain.the velocity of the stone given by V=9.8t.Draw its graph and find the velocity of the stone'4' seconds after start.

step by step explanation plz do fast​

Answer 1

Answer:

V= 39.2 m/s

Step-by-step explanation:

u=o , v =9.8 t, time = 4 ,a = 9.8 m/s2 ( due to gravity)

A= v-u/t

9.8= 9.8 t -0 /4

9.8*4=9.8t

9.8*4/9.8=t

4=t

V=9.8*4

=39.2m/s
