Answer:
A car is traveling with a velocity of 40 m/s and has a mass of 1120 kg. The car has Kinetic energy.
kinetic energy = 896000 joules
Explanation:
Kinetic energy is an energy a mass of body possess by reason of it motion. Kinetic energy depends on the mass and speed of a body . Kinetic energy is a scalar quantity, this means it has only magnitude but no direction.
Since the car is on motion the energy the car possess is a kinetic energy. Kinetic energy can be calculated using the formula below.
kinetic energy = 1/2 × mass × velocity²
kinetic energy = 1/2mv²
m = 1120 kg
v = 40 m/s
kinetic energy = 1/2 × 1120 × 40²
kinetic energy = 1/2 × 1120 × 1600
kinetic energy = 1792000/2
kinetic energy = 896000 joules
Given the mass and velocity of the travelling car, the energy it will posses is 896000J
Given the data in the question;
Mass of the car; [tex]m = 1120kg[/tex]
Speed or Velocity of the car; [tex]v = 40m/s[/tex]
Energy; [tex]K_E = \ ?[/tex]
Since the car is moving, it will posses a Kinetic Energy.
Kinetic Energy [tex](K_E)[/tex] is the form energy a matter or particle possesses due its motion. It is directly proportional to object's mass and the square of its velocity.
[tex]K_E = \frac{1}{2} mv^2[/tex]
We substitute our given values into the equation
[tex]K_E = \frac{1}{2}\ *\ 1120kg\ *\ (40m/s)^2\\\\ K_E = \frac{1}{2}\ *\ 1120kg\ *\ 1600m^2/s^2\\\\K_E = 896000kg.m^2/s^2\\\\K_E = 896000J[/tex]
Therefore, Given the mass and velocity of the travelling car, the energy it will posses is 896000J
