Homework Statement
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
Homework Equations
Determine the velocity of the 100 kg block when it has ascended 5 m
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 doesn't look right
acceleration = 9.81 (sin20 - 0.2cos20)
(500-100)/1.51
= 264.63m/s (first thing that makes me think I am 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
