Question

Lora (of mass 47.4 kg) is an expert skier. She
starts at 3.2 m/s at the top of the lynx run,
which is 107 m above the bottom.
What is her final kinetic energy at the bottom of the ski run?

Answer 1

Answer:

Kinetic energy is 242.7 Joule

Explanation:

m = 47.4 kg

v = 3.2m/s²

Now,

K.E. = 1/2 × m × v²

or, K.E. = 1/2 × 47.4 × 3.2²

or, K.E. = 242.7 Joule
