The speed of a stone falling after 6.0 seconds of free fall is 58.8 m/s.
How to calculate the speed of the stone under free fall?
The speed of a stone falling after 6.0 seconds of free fall is calculated by applying the following formula as shown below.
v = u + gt
where;
- u is the initial velocity of the stone
- v is the final velocity of the stone
- g is acceleration due to gravity
- t is the time of motion
The given parameters include;
time of motion, t = 6.0 s
acceleration due to gravity = 9.8 m/s²
The speed of a stone falling after 6.0 seconds of free fall is calculated as follows;
v = 0 + (9.8 m/s²) x 6 s
v = 58.8 m/s
