The car starts from rest at s = 0 and is subjected to an acceleration shown by the a–s graph. Draw
the v–s graph and determine the time needed to travel 200 ft.
Pegs A and B are restricted to move in the elliptical slots due to the motion of the slotted link. If
the link moves with a constant speed of 10 m/s, determine the magnitude of the velocity and
acceleration of peg A when x = 1 m.
The speed of a car increases uniformly with time from 50 km/h at A to 100 km/h at B for 10
seconds. The radius of curvature of the hump at A is 40 m. If the magnitude of the total acceleration
of the mass center of the car is the same at B as at A, compute the radius of curvature ρB of the dip
in the road at B. The mass center of the car is 0.6 m from the road.
The baseball player A hits the baseball at vA = 40 ft/s and θA = 60° from the horizontal. When the
ball is directly overhead of player B he begins to run under it. Determine the constant speed at
which B must run and the distance d in order to make the catch at the same elevation at which the
ball was hit.
Neglecting the size of the ball, determine the magnitude vA of the basketball’s initial velocity and
its velocity when it passes through the basket.
