Physics · Oct / Nov 2016 · Paper 11 · Question 9

Three objects P, Q and R have different masses and different speeds, as shown in the table. | | mass / kg | speed / m/s | |---|---|---| | P | 1.0 | 3.0 | | Q | 2.0 | 2.0 | | R | 5.0 | 1.0 | What is the order of increasing kinetic energy (smallest first) of the objects?

1. AP → Q → R
2. BP → R → Q
3. CR → P → Q
4. DR → Q → P
