A car with a mass of 1234 kg is traveling around a circular track with a radius of 100 m and a tangential velocity of 23 m/s. Determine the centripetal acceleration of the car.
Determine the centripetal force acting on the car.

If the ama of the inclined plane below is 2, calculate the ima and efficiency. ima = efficiency =

Awater slide of length l has a vertical drop of h. abby's mass is m. an average friction force of magnitude f opposes her motion. she starts down the slide at initial speed vi. use work-energy ideas to develop an expression for her speed at the bottom of the slide. then evaluate your result using unit analysis and limiting case analysis. express your answer in terms of the variables h, m, l, vi, f and appropriate constants. vf v f

According to newton’s law of universal gravitation, which statements are true? as we move to higher altitudes, the force of gravity on us decreases. as we move to higher altitudes, the force of gravity on us increases. as we gain mass, the force of gravity on us decreases. as we gain mass, the force of gravity on us increases. as we move faster, the force of gravity on us increases.
