Problem
A student investigates a low-friction cart by applying different horizontal forces and measuring the resulting accelerations. The data are plotted below.
Force (N): 1.0, 2.0, 3.0, 4.0, 5.0
Acceleration (m/s²): 0.47, 0.95, 1.45, 1.90, 2.40
Assuming the relationship between force and acceleration is linear, what is the best estimate of the cart's mass?
(a) 2.5kg
(b) 0.48kg
(c) 2.0kg
(d) 2.2kg
