By using the equation: Kinetic Energy = (1/2)mv^2, using m as 1000kg and v as 20ms^-1.We can calculate this value as follows: KE = (1/2)(1000)(20)^2This is equal to 2.0*10^5J (solved using a scientific ca...
First of all, it is important to remember that an object's acceleration is the rate of change of its velocity, not its speed. Velocity is a vector quantity and so must have a direction as well as a magnit...
