a body is fastened to a string 0.75 m long and is whirled to make 2 revolution per second on a horizontal plane with the other end of the string as center. FIND THE ACCELERATION
To find the acceleration in a uniform circular motion, we have the formula: A = v^2 / R. In this case, our v (velocity) is 2 rev/s and the R (radius) is 0.75 m. Substitute the values to the equation, we have: A = (2 rev/s)^2 / (0.75 m) = 5.33 m/s^2
