Answer:
An object that moves in uniform circular motion. Has a centripetal acceleration of 13m/s². If the radius of the motion is 0.02m what is the frequency of motion.
A racecar moving at a constant tengential speed of 60m/s. Takes one lap around a circular track in 50 seconds. Determine the magnitude of the acceleration of the car.
A stant pilot executes a uniform speed circular path in an airplane. The initial velocity of the plane is given by vo=2500i +3000j. One minute later the velocity of the plane is v=2500i-3000j. Find the magnitude of the acceleration.
The problem is not referring to an object in uniform circular motion but it deals with motion in two dimensions. The velocity of a particle moving in the x_y plane in the given by.
V=(6. 0t_4.0t²). İ+8.0j.
A. What is the acceleration when 3. 0 seconds.
B. When if ever the acceleration zero.
C. When if ever the speed zero.
I hope it's help full. It's too long.
