Homework help?? [ block on inclined plane ] 1. The problem statement, all variables and given/known data 002 (part 1 of 3) 10.0 points A 3.86 kg block slides down a smooth, fric- tionless plane having an inclination of 28◦ . The acceleration of gravity is 9.8 m/s2 . Find the acceleration of the block. Answer in units of m/s2. 003 (part 2 of 3) 10.0 points What is the block’s speed when, starting from rest, it has traveled a distance of 2.35 m along the incline. Answer in units of m/s. 004 (part 3 of 3) 10.0 points What is the magnitude of the perpendicular force that the block exerts on the surface of the plane at a distance of 2.35 m down the incline? Answer in units of N.
