describe the changes in the way energy is stored for a petrol car accelerating from rest to a velocity of 80km/h on a level road. assume no energy is lost to the surroundings.
Can the velocity of an object be negative when its acceleration is positive? What about vice versa? If yes, give examples in each case.
A truck is stopped at a stoplight. When the light turns green, it accelerates at 2.5 m/s2. At the same instant, a car passes the truck going 15 m/s. Where and when does the truck catch up with the car?
Two cars are travelling at constant speeds. A Neon is travelling at 15.6 m/s and a Corvette is travelling at 23.9 m/s. When a stopwatch is started, the Corvette is 13.5 meters behind the Neon. How long does it take the Corvette to catch the Neon? How far did the Neon travel before it was overtaken?
You drive in canada where the distance are marked in kilometers. The sign says you are 80km from Ottawa. You are at a speed of 75mi/h. Would you reach Ottawa within one hour, after one hour or later than hour?
Differentiate between the functions of the glass rod,the thread and the stirrer
A particle travels along a straight line with a constant acceleration. When, s = 4 ft, v = 3 ft/s and when
s = 10 ft, v = 8 ft/s. Determine the velocity as a function of position.
