As the spring-loaded mechanical catapult launches the drone, the ___________ energy store in the catapult decreases and the ___________ energy of the drone increases.
The total mass of the drone is 2.5 kg2.5\text{ kg}2.5 kg. The speed of the drone is 14 m/s14\text{ m/s}14 m/s.
Calculate the kinetic energy of the drone.
Use the equation: kinetic energy=0.5×mass×(speed)2\text{kinetic energy} = 0.5 \times \text{mass} \times (\text{speed})^2kinetic energy=0.5×mass×(speed)2
When the drone lands on a high-friction stopping pad, friction causes the temperature of the brake pad to increase.
Calculate the change in thermal energy of the brake pad.
Use the equation: change in thermal energy=mass×specific heat capacity×temperature change\text{change in thermal energy} = \text{mass} \times \text{specific heat capacity} \times \text{temperature change}change in thermal energy=mass×specific heat capacity×temperature change
How is the internal energy of the particles in the brake pad affected by the increase in temperature?
