Question 32
Easy

A motorized transport cart carries a load along an inclined outdoor track. The total weight of the cart and its cargo is 1200 N.

Figure 1 shows how the vertical height of the track changes with the distance travelled along the track.

A line graph showing the vertical height of a track. The vertical y-axis is labeled 'Vertical height (m)' and ranges from 0 to 10 with major gridlines every 1 m. The horizontal x-axis is labeled 'Distance along track (m)'. Point X is marked on the line at a vertical height of 1.5 m. Point Y is marked further along the line at a vertical height of 7.5 m.

Calculate the total work done against gravity when the cart moves from point X to point Y.
