Question

Tamsin strikes a golf ball so that it flies off with a speed of 60 m/s. The golf ball has a mass of 45 g. Calculate the kinetic energy of the golf ball.

Answer 1

81 joule is the kinetic energy of the golf ball.

K.E= mv²/2

K.E=0.045×60×60÷2

K.E=81 joule

Kinetic energy is a particular kind of power that is present in moving particles or objects. An object gains kinetic energy when work, which involves the transfer of energy, is done on it by exerting a net force. Kinetic energy is a property of motion that depends on the mass and speed of an object or particle. Motion is any combination of vibration, axis rotation, translation, and movement (along a path from one location to another). A body's translational kinetic energy, which is determined by multiplying its mass, m, by the square of its speed, v, is equal to 1/2mv2.
