A 0.54 kg particle has a speed of 5.0 m/s at point A and kinetic energy of 7.5 J at point B. What is
Wewaii [24]

<u>Answers</u>

(a)  6.75 Joules.

(b)  5.27 m/s

(c) 0.75 Joules


<u>Explanation</u>

Kinetic energy is the energy possessed by a body in motion.

(a) its kinetic energy at A?

K.E = 1/2 mv²

       = 1/2 ×  0.54 × 5²

       = 6.75 Joules.

(b) its speed at point B?

K.E = 1/2 mv²

7.5 = 1/2 × 0.54 × V²

V² = 7.5 ÷ 0.27

     = 27.77778

V = √27.77778

   = 5.27 m/s

(c) the total work done on the particle as it moves from A to B?

Work done = 7.5 - 6.75

                 = 0.75 Joules

What makes speed, velocity, acceleration, distance, and time different?​
LekaFEV [45]

Explanation:

  • Speed is the rate of change of distance with time.

            Speed = \frac{distance}{time}

  • Velocity is given as the displacement per unit of time:

             Velocity = \frac{displacement}{time}

Speed and velocity are similar but speed is a scalar quantity while velocity is a vector quantity. Speed has magnitude but does not point towards a specific direction. Velocity shows both magnitude and direction and it is a vector quantity.

  • Acceleration is given as the change in velocity with time. It is a vector quantity:

                Acceleration = \frac{change in velocity}{time}

  • Distance is how far a body moves. It is scalar quantity.
  • Time is the duration of an event. It is a scalar quantity.
