Asmall ball is attached to the lower end of a 0.800-m-long string, and the other end of the string is tied to a horizontal rod. the string makes a constant angle of 49.3° with the vertical as the ball moves at a constant speed in a horizontal circle. if it takes the ball 1.45 s to complete one revolution, what is the magnitude of the radial acceleration of the ball?

According to newton’s first law of motion, which force is expected to cause a body to accelerate?

Agas contained within a piston-cylinder assembly undergoes three processes in series: process 12: compression with pv= constant from 1 bar and 1 liter to 4 bar. process 23: constant pressure expansion to 1 liter. process 31: constant volume calculate the pressure and volume at each state, and sketch the processes on a p-vdiagram labeled with pressure and volume values at each numbered stat

Suppose an objects initial velocity is 10m/s and it’s final velocity is 4 m/s. mass is constant. what can best be concluded about the object based in the work-energy theorem
