Anyway

1. A car parked 40Km east of a train station travels westwards for 4 hours. If after 4 hours the car is observed to be 100Km west of the station, determine the average

**velocity**of the car

2. A skier accelerates down a hill from 2.5 m/s to 8.9 m/s in 3.4s. Determine the distance the skier tavelled during his acceleration.

3. A truck, traveling at 22 m/s, accelerates constantly while going through a tunnel. If the truck's acceleration is 4.0 m/s^2 and it exits the tunnel with a velocity of 35 m/s, determine the length of the tunnel

4. A pony running at 3.0 m/s, accelerates uniformly at 3 m/s^2 for 5 s. What is the

**displacement**during the second second

Any help would be greatly appreciated, and there is more stuff to come...
