Question

A 1500kg Ford truck travels at a speed of 21m/s, what is the K.E and how do you calculate the K.E?

Answer 1

The kinetic energy (K.E) of an object is given by the equation:

K.E = 1/2 * m * v^2

Where:
m = mass of the object (in kilograms)
v = velocity of the object (in meters per second)

In this case, the mass of the Ford truck is given as 1500 kg, and the velocity is given as 21 m/s. Plugging these values into the equation, we get:

K.E = 1/2 * 1500 kg * (21 m/s)^2

Calculating this expression:

K.E = 1/2 * 1500 kg * (441 m^2/s^2)

K.E = 330750 J

Therefore, the kinetic energy of the Ford truck is 330750 Joules.
