CIRCULAR MOTION PHYSICS: An object traveling along a circular path has a speed of 30 m/s at t=0sec...

at any time t, let alone t = 2, the speed of the object will be 30 m/s.I hope this helps!......
If its radial acceleration remains constant at 4 m/s^2, what is its speed at t=2 seconds.

The final answer should be 30 m/s, but I do not know how to find that. FIRST PERSON TO ANSWER WITH WORK GETS ALL THE POINTS!!!

Note that in order for an object traveling at a velocity of v to stay in a circle of radius, a constant force mv^2/r must be directed towards the center of the circle.

Since mv^2/r must be constant and because m and r are constants, v^2 must also be constant. This shows that the speed of the object remains constant. Therefore, at any time t, let alone t = 2, the speed of the object will be 30 m/s.

I hope this helps!
