Question

When a stone is falling from a mountain, its initial velocity is zero and the acceleration

to gravity is 9.8 m/s. Velocity of the stone is given by v = 9.8 t

Draw its graph and find the velocity of the stone 4 second after start.​

Answer 1

Answer:

As we can see after 4sec the velocity of Stone is 39.2 m/s

Step-by-step explanation:

the velocity of the stone is given

v = 9.8t

we have to find velocity of stone after 4 seconds

, let consider t = 4

v = 9.8 × 4

v = 39.2 m/s
