As illustrated in Fig. 1.1, an aircraft tows a glider along a runway.
Fig. 1.2 displays the glider’s speed during the initial 12 s of the motion.
(a)[2]
Describe the glider’s motion during the first 12 s.
(b)[3]
During the first 6.0 s of the motion, the resultant force on the glider is 1800 N. Using the increase in speed over the first 6.0 s, calculate the mass of the glider.
(c)[2]
Determine the distance travelled by the glider during the first 6.0 s of its motion.
(d(i))[1]
State what the term ‘convection current’ means.
(d(ii))[1]
Suggest how the convection current that supports the glider develops.
Worked solution & mark scheme
This 9-mark question has a full step-by-step worked solution and mark scheme. One marking point: “Uniform/constant acceleration during the first 6 s or acceleration = 3.7 m s^{-2}” …
