KE= 1/2mv2
KE=1/2(4)82
KE=2(8)2
KE=162
KE= 256 J
So the total is 256 J of Kinetic and Potential Energy
The bike's kinetic energy is 45 joules.

The formula for kinetic energy is 1/2 x mass x speed squared. Just replace the mass and the velocity with the numbers. Since standard SI units are used, the answer will be in joules.
the correct answer is (0.148)(40)^2 / 2 just take the Quiz
You can assume for this problem that "total energy" refers to "total mechanical energy", i.e., potential energy + kinetic energy.
The bike's kinetic energy is 45 joules.

Kinetic Energy = 1/2 mass kg * Velocity squared KE = 1/2mV^2 KE = 1/2(70 kg)(6 m/s)^2 = 1260 Joules
Use the formula e=1/2mv2 Where m=mass in kg v=velocity in metres per second the answer will be in joules, that is e
Kinetic energy is dependent on which point you are talking about. When it is about to be dropped, kinetic energy is zero. When it reaches almost hits the ground, there is maximum kinetic energy.
The formula for kinetic energy is 1/2 x mass x speed squared. Just replace the mass and the velocity with the numbers. Since standard SI units are used, the answer will be in joules.
Kinetic energy is the energy a body has when in motion. The faster the speed, the greater the kinetic energy. The formula for kinetic energy is KE = 1/2mv2, where m is mass in kg, and v is velocity in m/s.
The object's kinetic energy is 78.4 joules.
Kinetic energy = 1/2 m V2 = 1/2 (3) (2)2 = 6 joules
The energy of motion is called kinetic energy.
Kinetic energy = 1/2 x mass x velocity2. Mass in Kg, velocity in meters/sec, energy in Joules
Kinetic energy is the energy a moving mass has, equal to 0.5 m v^2If the mass m is in kg and the speed v is in metres/sec, the kinetic energy will be in Joules.So a car of 1000 kg travelling at 20 m/s has a kinetic energy of 0.5*1000*400 or 200,000 Joules.
