Question 21

A student uses a newtonmeter to measure the force required to pull a toy car up a ramp. Before attaching the car, when no force is applied, the newtonmeter has a zero error and reads +0.4 N+0.4\text{ N}+0.4 N. While pulling the toy car at a constant speed, the tension measured by the newtonmeter is recorded as 12.8 N12.8\text{ N}12.8 N. The distance the car is pulled along the ramp is 4.5 m4.5\text{ m}4.5 m. Calculate the actual work done to pull the car up the ramp, taking into account the zero error of the newtonmeter. Use the equation: \

\text{work done} = \text{force} \times \text{distance}{\char"24}$
