- Lab Report - Perform experiment to find acceleration of a cart on three different types of slopes: Flat, Inclining, and Declining.
- Relevant Equations
- Type 1(Flat): a = m2g - (coefficient of friction)m1g / m1 + m2
Type 2(Inclining): a = T - (coefficient of friction) m1g(cos(theta)) - m1gsin(theta) / m1
Type 3(Declining): a = mg(sin(theta)) - (coefficient of friction)mg(cos(theta)) / m
I am trying to solve accelerations of a cart on these different slopes. I don't understand how it is possible without knowing the coefficient of friction, but my teacher says it is (very cryptically I might add). Can anyone help me understand this? Thanks.
