1 (a) A student places a trolley at the top of a runway, as shown in Figure 1.
trolley
light gate
timer
runway 00:00:00
Figure 1
The student had to lift the trolley through a height of 26 cm to put it at the top of
the runway.
The gravitational potential energy, ΔGPE, of the trolley increases by 4.1 J when
lifted to the top of the runway.
The gravitational field strength, g, = 10 N / kg.
(i) Show that the mass of the trolley is about 1.6 kg.
Use the equation

, (ii) The student releases the trolley and the trolley moves down the runway.
The student assumes that all the extra gravitational potential energy, ∆GPE,

stored at the top of the runway is transferred to kinetic energy at the end of
the runway.
Calculate the expected value of the velocity of the trolley at the end of
the runway.
Use the equation

expected velocity = ...................................................... . . . . . . . . m / s
(iii) The light gate, shown in Figure 1, is used to determine the actual velocity of
the trolley at the end of the runway.
The actual velocity at the end of the runway is less than the expected velocity
as calculated in (ii).
Suggest one way to reduce the difference between the actual velocity and
the expected velocity.
