(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

The block of mass 500 kg is released from rest at the top of the slope

It slides down a ramp of angle 20degrees

It raises a block weight of 100kg

The coefficient of kinetic friction between the 500 kg mass and the ramp is 0.2

2. Relevant equations

Determine the velocity of the 100 kg block when it has ascended 5 m

3. The attempt at a solution

Hi.

Im not very good with maths and physics and i'll freely admit that. I just need somehelp in prodding me in the right direction

this is what i did so far and it really doesnt look right

acceleration = 9.81 (sin20 - 0.2cos20)

(500-100)/1.51

= 264.63m/s (first thing that makes me think im doing the wrong thing)

then v squared = 0 + (2*264.63*5)

= 51m/s

Now even to someone as thick as me that looks completely wrong. So can someone help me out
