Question

a car was running with velocity of 20 m/s what will be its velocity after 30 seconds if its acceleration is 5 m/s 2

Answer 1

Answer:

If the car travels 1200 metres in 30 seconds, its average speed is 40 m/s. Since its initial speed is 20 m/s its final speed is 60 m/s. Thus its acceleration is (60–20)/30 = 1.33 m/s².

Answer 2

1.33 m/s
