Question

When a stone is falling from mountain its initial velocity is zero and acceleration due to gravity is 9.8 metre per second square velocity of the stone is given by v is equal to 9.8 draw its graph and find the velocity of stone 4 seconds after start.​

Answer 1

Answer:

6

Step-by-step explanation:

Answer 2

Answer:

velocity of stone after 4sec is 39.2m/s

Step-by-step explanation:

for freely falling body initial velocity is zero..

but due to gravity it increases by 9.8m/s^².

so after 4 sec it is 4x9.8=39.2m/s.

can you give this brainliest answer.
