km hr

v2 = 120

km hr

t = 15 s

d = v1 t +

d = 291.67 m

Problem 12-2 A car starts from rest and reaches a speed v after traveling a distance d along a straight road. Determine its constant acceleration and the time of travel. Given: Solution: v = 2a d

d = 500 ft

v a = 2d t = v a

a = 6.4

v = at

t = 12.5 s

Problem 12-3 A baseball is thrown downward from a tower of height h with an initial speed v0. Determine the speed at which it hits the ground and the tim
