a)
Kinetic energy (KE) = 1/2 m v^2
Where:
m = mass = 1260 kg
v = speed = 66.3 km/h = 18.42 m/s
Replacing:
KE = 1/2 (1260 kg ) (18.42 m/s )^2 = 213,756.7 J
Answer:
Kenetic
Explanation:
Potentiak is at the start
kenetic is stores energy being released
Hey there mate :)
Even if two persons are given the same work load, the speed of the work done gets different by the energy of those persons.
No one is sure that he/she can complete the work within the time. He may or may not.
Also, the physical characteristics makes the work different. If one person has so much power to work all day, the other person may not have.
Therefore, <em>even if two persons do the same amount of work , they may have different power</em><em>.</em>
The answer to this question is that --- The momentum possessed by a body is generally defined as the product of its mass and velocity.
Momentum is a vector and it also has magnitude as it is the product of the multiplication of the mass and velocity.
