Kinematics: Rectilinear Motion
Rectilinear motion problems deal with an object that moves laterally, or horizontally and does not rotate about its center of mass.

· 10-3 A conveyor 60 m long is inclined at an angle of 18° to the horizontal and deposits material 8 m below its top end. Determine the distance and displacement of material carried by this conveyor.
· 10-10 A car traveling at a constant speed of 90 km/h takes 8 seconds to travel through a constant radius curve as shown in Figure P10–10. Determine the average acceleration of the car.
· 10-13The velocity of a particle at t = 2 s is 50 m/s
; at t = 6 s, it is 50 m/s
. Calculate the average acceleration during the time interval.
· 10-20 A motorcycle accelerates at 1.6 m/s2 to reach a velocity of 20 m/s in a distance of 50 m. Determine its initial velocity and time elapsed.
vo = 15.5 m/s t = 2.82 s
