Hey, everyone I am new to this site... I found it because I am despreate need of help in physics. I just started it this year and am having extreme difficulty. My average in my advanced math class is 87% but I just can't seem to get physics. I don't like to blame teachers but to be honest he is not very helpful or easy to understand. I have the answers for the current problems because he gave them to us but I need a lot of help understanding the process.(adsbygoogle = window.adsbygoogle || []).push({});

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 averagevelocityof 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, travelling 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 thedisplacementduring the second second

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