... A skateboarder rolls from rest down an inclined ramp that is 15.0 m long and inclines above the horizontal at an angle of q = 20.0o. When she reaches the bottom of the ramp 3.00 s later her speed is 10.0 m/s. Show that the average acceleration of the skateboarder is g sin q, where g = 9.81 m/s2. ...

... Uniform circular motion can be described as the motion of an object in a circle at a constant speed. As an object moves in a circle, it is constantly changing its direction. At all instances, the object is moving tangent to the circle. Since the direction of the velocity vector is the same as the d ...
