Net Acceleration for Non Uniform Circular Motion
A particle is...
Question
A particle is constrained to move in a circle with a 10-meter radius. At one instant, the particle's speed is 10 m/s and is increasing at a rate of
10
m
/
s
2
. The angle between the particle's velocity and acceleration vectors is.
