A particle of mass m=1kg moves counterclockwise in a horizontal circle of radius r=1m with uniform speed of 1 m/s. Determine the velocity, acceleration, total force and the component of the the total force on the particle in direction of its velocity as a function of the angle.
a = v*v / r
The Attempt at a Solution
Velocity = - 1 m/s
(negative sign is to indicate the direction of the particle moving counterclockwise)
Acceleration, a = 1
Total force,F = 1N
Is there anyone can help me to confirm my answer? Especially the velocity....
