Calculate the distance travelled by a car with a velocity of 30m/s and it increase its speed to 60 m/s in 2 hours.assume acceleration is constant.
Answered by Scott
uniform acceleration means that the average speed is the numerical average of the initial speed and the final speed

average speed ... (30 + 60) / 2 = 45

60 s in a min ... 60 min in an hr

distance = 45 * 60 * 60 * 2 (meters)
