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.
