A sledge accelerates, due to gravity, from rest down a frictionless slope. Air resistance can be ignored. The slope is at an angle of 6.9° to the horizontal, as shown.
Complete the free‐body force diagram below for the sledge.
The slope has a total length of 60m
i) Show that the initial acceleration of the sledge along the slope is about 1 m s−2
Initial acceleration = ........................................ (2)
ii) Determine the speed of the sledge at the end of the slope.
Speed at end of slope = .................................... (2)
iii) Determine the time taken for the sledge to travel to the end of the slope.
Time taken = ...................................... (2)
