Question

The expression for the acceleration of the cart for the experiment you did in lab is

a =

where

m1 + m2

is kept constant throughout.

(a) Consider the situation when friction force is zero. What is the expression for the acceleration of the cart now? (Use the following as necessary: m1, m2, and g.)

If you triple the hanging mass, m1, (so m=3m1) what would then be the expression for acceleration?

(b) Consider the situation when friction force is non-zero. What is the expression for the acceleration of the cart now? (Use the following as necessary: m1, m2, f, and g.)

If you now triple the hanging mass m1, (so m = 3m1) how will the value of the denominator for the expression for the acceleration change?

What is the expression for the acceleration now? (Use the following as necessary: m1, m2, f, and g.)

Explanation / Answer

here

F = m1 * g

F = (m1 + m2 ) * a

a = m1 * g / ( m1 + m2)
