Question

Solve questions 1,2 and 3

1. The v-t graph for the motion of a car as it moves along a straight road is shown. Draw the s t graph and determine the average speed and the distance traveled for the 30-s time interval. The car starts from rest at s v (ft/s) 60 +30 40 t (s) 10 30 z. A particle, originally at rest and located at point (3 ft, 2 ft, 5 ft), is subjected to an [M + 12% } ft/S Determine the particle's position (x, y, z) at t- tion of a S. 3. The ball at A is kicked such that 8A -30 If it strikes the ground at B having coordinates x-15ft, and y-9ft, determine the speed at which it is kicked and the speed at which it strikes the ground.
