At the bottom of a dip, the kinetic energy (KEKEKE) of a roller coaster cart is 18 000 J18\ 000\text{ J}18 000 J.
The mass of the cart is 250 kg.
Calculate the velocity (vvv) of the cart at this point.
Use the equation:
v2=2×KEm v^2 = \frac{2 \times KE}{m} v2=m2×KE82 exam-style questions on Edexcel GCSE Physics 3.1 Energy stores and calculations. Each one has a worked solution and a mark scheme showing where the marks go.
