A toy car with a mass of 3 kg starts at rest. A spring performs 220 J of work on the car. Using the Work-Energy Theorem determine the approximate final velocity of the toy car.
a) 660 m/s
b) 147 m/s
c) 73 m/s
d) 12 m/s

Respuesta :

The final velocity of the toy car given the data from the question is 12 m/s (Option D)

What is velocity?

This is defined as the rate of change of displacement with time.

However, the velocity of an object is related to its energy according to the following equation

E = ½mv²

Where

  • E is the energy
  • m is the mass
  • v is the velocity

How to determine the velocity

From the question give above,the. following data were obtained

  • Energy (E) = 220 J
  • Mass (m) = 3 Kg
  • Velocity (v) = ?

E = ½mv²

220 = ½ × 3 × v²

220 = 1.5 × v²

Divide both side by 1.5

v² = 220 / 1.5

Take the square root of both side

v = √(220 / 1.5)

v = 12 m/s
