If a cart is released from rest at a 10 meter incline and takes 28 seconds to travel down this incline.
1. Calculate the average speed of the cart?
2. calculate the instantaneous velocity of the cart at the end of the 10 meters(this value should be twice the value in question 1
3. calculate the acceleration of the cart
4. how long does it take the cart to travel the first 5 meters down the track? (the answer is not 14 seconds)

The definition of average speed should tell you the answer to #1. That will also lead to the answer of #2. If you are unwilling to make any effort, you have come to the wrong place
