Answer:
Time taken to accelerate to 48 m/s = 8 seconds
Explanation:
Initially the object is moving south at =
So, initial velocity of the object =
Acceleration caused by the force = 4
Final velocity towards south =
Using equation of motions:
where
final velocity
initial velocity
acceleration
time
Plugging in values.
Subtracting both sides by 16
Dividing both side by 4.
∴
Time taken to accelerate to 48 m/s = 8 seconds
