Question 52
Easy

A robotic lander with a mass of 800 kg is descending towards the surface of a moon, as shown in Figure 1.

Figure 1: Diagram showing a robotic lander of mass 800 kg descending from position A to position B. The horizontal distance between position A and B is 3.5 km. The vertical height of the descent is 1.2 km. The speed of the lander at position A is 60 m/s, and at position B it is 20 m/s.

Use the data in Figure 1 to calculate the decrease in kinetic energy of the lander as it descends from position A to position B.
