Question

For a freely falling object dropped from rest, what is the acceleration at the

Answer 1

The acceleration of the object after 3 seconds of fall is -9.8 m/s².

The given parameters;

• initial velocity of the object, u = 0
• time of motion of the object, t = 3 seconds

Acceleration is the change in velocity per change in time of motion.

The acceleration of the object after 3 seconds of fall is calculated as follows;

• Since the object is in free fall, the object experiences only acceleration due to gravity.
• the magnitude of this acceleration due to gravity is 9.8 m/s²
• the direction of this acceleration is downwards

 

Thus, the acceleration of the object after 3 seconds of fall is -9.8 m/s².
