You can use the formula for kinetic energy to verify the total kinetic energy (KE = 0.5mv2). Then, assuming all the energy is converted to (gravitational) potential energy, use the formula for potential energy, and solve for height. (PE = mgh)
To measure kinetic energy:Let us suppose an object of mass m moving wtih velocity vKinetic Energy of that object= mv2/2
The kinetic energy of the bicycle can be calculated using the formula: KE = 0.5 * mass * velocity^2. Plugging in the values: KE = 0.5 * 10 kg * (3 m/s)^2 = 45 Joules. So, the kinetic energy of the bicycle is 45 Joules.
When the velocity is tripled to 15 meters per second, the kinetic energy will increase by a factor of 9 (3^2) since kinetic energy is proportional to the square of velocity. So, the kinetic energy will be 225 joules (25 * 9) when the velocity is tripled.
The quantities involved in kinetic energy are mass and velocity. Kinetic energy is calculated as 1/2 the mass of an object multiplied by its velocity squared. The unit of measurement for kinetic energy is joules.
The unit used to measure the average kinetic energy of a substance is joules (J).

The object's kinetic energy is 2,500 joules.
Kinetic energy is directly proportional to the square of velocity, so the kinetic energy will increase. If the velocity increases from 20 m/s to 32 m/s, the kinetic energy will increase by a factor of (32/20)^2 = 2.56. Therefore, the kinetic energy will be 4500 Joules * 2.56 = 11520 Joules when the velocity is 32 m/s.
