1. The velocity Vector of any object in uniform circular motion is drawn as a tangent(Tangent) on the circumference of the circle which shows that the size of the velocity is constant but the object is accelerating. 2. Acceleration can be calculated as either change in speed( size of velocity)with time or change in with time. 3. Acceleration in uniform circular motion is caused by a velocity vector which is constantly changing

An undiscovered planet, many lightyears from Earth, has one moon in a periodic orbit. This moon takes 20.0 days on average to complete one nearly circular revolution around the unnamed planet. If the distance from the center of the moon to the surface of the planet is 2.420 × 10° km and the planet has a radius of 4.100 × 10³ km, calculate the moon's radial acceleration a. a = m/s? & TOOLS x10

1. Consider an object on some trajectory r(t) and define v = r' as the velocity with speed v = [r'|. (a) Show that we can write v = vT. (b) Show that we can write the acceleration as a = arT + anN where ar and an are the tangential and normal acceleration components that are func- tions of the speed and curvature. Explain why an object with constant speed can still experience an acceleration. (c) Consider a trajectory r(t) = (t² – 1,t – t³). Compute the curvature as well as the tangential and normal components of the acceleration.

4. Harnessing wind power has become an effective alternative to finding and refining fossil fuels. These wind turbines are now found all over Ontario. One of these turbines has a blade with an 8 metre diameter. The maximum height from the ground to the tip of the blade is 26 m. At an average wind speed, the blade makes 20 rotations every minute. Assuming that the tip of the blade starts at the lowest point, determine an equation for the height versus time.
5. Consider an aircraft flying due east along the equator. Define an Earth-fixed coordinate system FE at zero longitude and zero latitude, and a local horizontal coordinate system F, fixed to the center-of-gravity (CG) of the aircraft. Describe the relationship between the axes of FE and FH at the instant the aircraft is at zero longitude and zero latitude, and again at the instant it is at 180 deg east longitude and zero latitude. 6.
