Report in dynamicsProblem 1 (12-52) A car travels up a hill with the speed shown. Determine the total distance the car travels until it stops (t= 60 s). Plot the a-t graph

Required : a-t graph

Solution :

s = lw + bhs = 10 (30) + (30)(10)s = 450 mFor a : For 0s t 30 s ;For 30s t 60 s; a = 0 m/s 2 see v-t graph

a= V/t = 10/30 = 0.33 m/s 2

V-t graph
