A. In a uniform circular motion, which of the following quantities are constant: speed, instantaneous velocity, tangential velocity, radial acceleration, tangential acceleration?

	Radial acceleration
	Speed
	Instantaneous velocity
	Tangential acceleration

B. Which of these quantities is zero throughout the motion?

Hi, I need some help with this problem. Please post at least part(a) ASAP.

An object undergoes uniformly accelerated motion from point x1 = 4m at time t1 = 2 s to point x2 = 40 m at time t2 = 7 s.
(a) If the magnitude of the instantaneous velocity at t1 is v1 = 3m/s, what is the instantaneous velocity v2 at time t2?


(b) Determine the magnitude of the instantaneous acceleration ofthe object at time t2.

The position versus time for a certain object moving along the x-axis is shown. The object's initial position is -2 m.

(a) Find the instantaneous velocity at 0.5 s. Answer in units of m/s.

(b) Find the instantaneous velocity at 2 s. Answer in units of m/s.

(c) Find the instantaneous velocity at 4.5 s. Answer in units of m/s.

(d) Find the instantaneous velocity at 8.5 s. Answer in units of m/s.
