If an object from a tall building falls, it will take it 4.995 seconds to reach a speed of 49 m/s.
How to calculate time in projectile?
The time taken for an object to fall can be calculated using the following equation of motion:
V = u + at
Where;
- V = final velocity
- u = initial velocity (Om/s)
- a = acceleration due to gravity (9.81 m/s²)
- t = time
According to this question, an object from a tall building falls. The time it would take to reach a speed of 49m/s can be calculated as follows:
49 = 0 + 9.81(t)
49 = 9.81t
t = 49/9.81
t = 4.995s
Therefore, if an object from a tall building falls, it will take it 4.995 seconds to reach a speed of 49 m/s.
