Question

A bus moves from rest with a uniform acceleration of 2 meters per sec for a uniform rate of 1 meters per sec . it then accelerate at a uniform rate of 1 meters per sec for another 15 sec . it continues at a constant speed for 70sec and finally comes to rest in 20sec by uniform deceleration.draw the velocity time graph of the motion using the information given above from your graph . calculate the total distance traveled, the average speed for the whole journey, average retardation as the body is about to rest, the maximum speed attained during the journey

Answer 1

Answer:

What is the average speed in kilometers per hour for a horse that gallops a distance of 15 km in a time of 30 min? Average speed = 15 km/30 min = 15 km/0.5 h = 30 km/h.
