Question

I’m trying to calculate the speed of a block on top of a ramp (frictionless surface). It goes from a flat surface, up a ramp (1.2m), and then it levels off. I have the initial speed of (5.99m/s), the mass (2.3kg), the GPE at the top of the ramp (27.048KJ). I’m trying to calculate the speed of a block on top of a ramp (frictionless surface).

Explanation / Answer

Apply conservation of energy

K.E + P.E = constant

0.5*2.3*5.992 = 27.048+ 0.5*2.3*V2

V = 3.515 m/s
