The kinetic energy of delivery drone P is 50 J.
Delivery drone Q has the same mass but double the speed of drone P.
What is the kinetic energy of delivery drone Q?
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
