Question

Julie is cycling at a speed of 3.4 meters/second. If the combined mass of the bicycle and Julie is 30 kilograms, what is the kinetic energy?

Answer 1

Velocity=3.4m/sec
Mass=30kg
so kinetic energy=1/2mv^2
=1/2×30×3.4×3.4
=15×3.4×3.4
=15×11.56
=173.4 kg m per second square

enjoy pal

Answer 2

the formula for kinetic energy isk=1/2mv2. so u can square your distance then multiply it by mass and divide it by two
