Question:

A block of mass 2 kg slides down ramp 1 with a height of 3 m. It then slides for 1 m on a surface with a kinetic coefficient of friction of 0.4. Next the block slides up a frictionless ramp 2. What is the potential Energy of the block at the top of Ramp 1

Answers

Answer:PE = 58.8,JExplanation:The potential energy at the top of ramp1 can be found by the application of the formula PE = mghWhere PE =potential energy m = mass of block = 2kgg = acceleration due to gravity = 9.80m/s²h = height of the top of the ramp from its bottom where the block is initially positioned = 3mPE = 2×9.8×3 = 58.8J
