Question

which point has the most ke?
e
b
c
a

Explanation:

Kinetic Energy (KE) depends on speed, with $KE=\frac{1}{2}mv^2$. On a rollercoaster, the lowest point has the highest speed, as gravitational potential energy converts fully to KE. The first bottom point (matching option E) is the lowest, so it has maximum KE.

Answer:

E
