A 3.72 kg block slides down a smooth, frictionless plane having an inclination of 35. The acceleration of gravity is 9.8 m/s2 . Find the acceleration of the block. Answer in units of m/s2. What is the block’s speed when, starting from rest, it has traveled a distance of 3.42 m along the incline. Answer in units of m/s. What is the magnitude of the perpendicular force that the block exerts on the surface of the plane at a distance of 3.42 m down theincline? Answer in units of N
