(a(i))[1]
Explain what the term work done means.
(a(ii))[1]
Define what power means.
(b(i))[3]
Calculate the kinetic energy, in kJ, of the carriage and passengers as they travel towards the slope.
(b(ii))[2]
Show that the increase in potential energy of the carriage and passengers is $24\,\text{kJ}$.
(b(iii))[1]
Calculate the work done against the resistive force as the carriage travels up the slope.
(b(iv))[2]
Use your result in (iii) to calculate the resistive force acting against the carriage as it moves up the slope.
