Expert Solution
Introduction
Given,
Mass of the cart, say M = 3.9 kg
From the figure,
Length of the ramp, say L = 130 cm = 1.3 m [1 m=100 cm]
Inclination of the ramp, say = 5o
Horizontal distance of the ramp from the stopper, say D = 200 cm = 2 m
The problem can be answered by applying the laws of motion and the equations of motion.
