51 Km/h with velocity the truck is moving.
KE = 1/2mv^2
(23)(1/2)×1000×15^2 = (1/2)2000×v^2
v = [tex]\sqrt(15*15*23/2)[/tex] = 50.867km/h => 51km/h
velocity is the measurement of a body's "pace of change of displacement in relation to time" when the body is traveling along a straight route.
velocity is a vector. As a result, when the displacement to time ratio for linear velocity is determined, it provides both the direction and the magnitude.
Linear velocity and rotational velocity are two ways to categorize velocity. The linear velocity of a body moving in a straight line is the rate at which its displacement is changing. There is no dispute that every object in motion has a linear velocity. Angular velocity only applies to things traveling in circles, not to those on straight trajectories. The rate of change of the angular displacement with respect to time is referred to as the angular velocity.
