A ball at the end of a string is swinging in a horizontal circle of radius 1.5m. The ball makes exactly 10.00 revolutions per second. What is its centripetal acceleration?

Consider motion in one dimension. (the sign of the vector quantities is their direction indicator.) an object moves in the positive x-direction with speed 2.9 m/s for 4.5 s. it stops for 3.8 s and then moves in the negative x direction with speed 2.8 m/s for 4 s. what is the total distance traveled by the object in units of meter? enter a number with two digits behind the decimal point.
