<h3>Answer:</h3>

100 Joules

<h3>Explanation:</h3>

The question is testing on how to calculate work done;

We are given;

  • Mass of an object is 5 kg
  • Distance moved is 2 m

We are required to calculate the amount of work done.

How do we calculate work done?

  • Work done is the product of force and distance.
  • Therefore without distance covered no work is done.
  • Work done = Force × distance
  • Additionally, it is measured in joules or Nm

In this case;

Force = mass × 10 N/kg

         = 5 kg × 10 N/kg

         = 50 N

Therefore;

work done = 50 N × 2 m

                  = 100 Joules

Thus, the work done in lifting the object is 100 Joules

Answer:

The maximum speed of the heart wall during the motion is 0.032 m/s

Explanation:

Given:

A = amplitude of vibration = 1.7 mm = 1.7x10⁻³m

f = frequency = 3 Hz

The angular velocity is:

w=2\pi f=2\pi *3=18.85Hz

The maximum speed of the heart wall during the motion is equal to:

V=Aw=1.7x10^{-3} *18.85=0.032m/s
