i Have 3 problems here I need some help on if anyone can do at least one it is much appreciated

1. A ball is thrown straight up. What will be the instantaneous velocity at the top of its path? What will be its acceleration at the top? Why are your answers different?

2. You drive to the city at an average speed of 40 km/h and return at an average of speed of 60 km/h. Find your average speed for the entire trip. Explain why the answer is not 50 km/h.

3. Harry averages 40 km/h for the first half of his car trip. How fast should he drive on the remaining half of the trip to have an average speed of 80 km/h for his trip?
