5. ### A person travels by car from one city to another with different constant spe?

Just calculate the individual distances and sum them for the total distance: d = 45/60 * 55 + 16/60 * 95 + 55/60 * 50 km Then calculate the total time t (3 trip times plus 30 min). Average speed = d/t

6. ### a ball rolls off a horizontal roof at 15m/s how far will the ball have fallen vertically when it reaches a spe?

Speed vertically of 24m/sec will take a height of (v^2/2g) = 29.388 metres to attain. The v^2 is 24^2, not 15^2, and g used is 9.8.
