Calculate its velocity if it travels a distance of 0.5m while accelerating. 6. An aircraft is travelling along a runway at a velocity of 25m/s. It accelerates at a rate of 4m/s2 for a distance of 750m before taking off. Calculate its take-off speed. 7. A car is travelling at a speed of 21m/s. It accelerates at an average rate of 3m/s2 for a time of 4 seconds. Find the distance it travels. 8. A car accelerates at a rate of 10m/s2 for a time of 4s. It reaches a speed of 52 m/s.

Because both rides will not continue to move in circles if there is no force pulling them towards the center and that is the job of the centripetal force. 6.

http://www.physicsclassroom.com/mmedia/circmot/rcd.cfm What is ‘g force’ in physics? G‚ in physics‚ a symbol relating to gravity. A capital G indicates the gravitational constant‚ as explained in the article GRAVITATION. A lower-case g stands for the acceleration imparted by gravity at the earth’s surface. An acceleration of 1 g is 32. 1 feet per second per second (9.8 m/s2). Fliers and astronauts may experience accelerations many times larger than 1 g. These accelerations are usually expressed

SAMPLE PROBLEMS: 111-SET #1 VECTOR ADDITION‚ SUBTRACTION 01-1 1). A man is able to row a boat at 3 mph in still water. If he rows his boat pointed straight across a river with a current of 4 mph‚ what is his net velocity? If the river is 0.5 miles wide‚ at what point will he land on the other side? Solution: The first step in problem solving is to identify the problem type. In this problem we are asked for a ‘net velocity.’ Since velocities behave as vectors‚ then we have a vector addition
