Equations of Motion: Translation Learning Goal: To use the equations of motion as they relate to linear translation of an object to determine characteristics about its motion. The car shown has a mass of m= 1200 kg and a center of mass located at G. The coefficient of static friction between the wheels and the road is us 0.240. The dimensions are a = 1.05 m. b= 1.65 m, and c= -0.350 m Assume the car starts from rest, the...
2. For each of the following motions draw a motion diagram, a position-vs-time graph, and a velocity-vs-time graph. a. A car starts from rest, steadily speeds up to 40 mph in 15s, moves at a constant speed for 30s, b. then comes to a halt in 5s A rock is dropped from a bridge and steadily speeds up as it falls. It is moving at 30 m/s when it hits the ground 3s later. Think carefully about the signs.

Q5: A flatbed truck starts from rest on a road whose constant radius of curvature is 30 m and whose bank angle is 1°. If the constant forward acceleration of the truck is 2 m/s, determine the time t after the start of motion at which the crate on the bed begins to slide. The coefficient of static friction between the crate and truck bed is -0.3, and the truck motion occurs in a horizontal plane. (5.58 s 10°
Consider the graph of force, F, vs. time, t, above, which leads to an impulse, I. The hashmark on the vertical axis denotes a value F0=15 N.
