The speed of a rocket just after being launched is 12 m / s.
drek231 [11]

This question involves the concepts of the equations of motion, kinetic energy, and potential energy.

a. The kinetic energy of the rocket at launch is "3.6 J".

b. maximum gravitational potential energy of the rocket is "3.6 J".

<h3>a. KINETIC ENERGY AT LAUNCH</h3>

The kinetic energy of the rocket at launch is given by the following formula:

K.E=\frac{1}{2} m v_i^2

where,

  • K.E = initial kinetic energy = ?
  • m = mass of rocket = 0.05 kg
  • v_i = initial speed = 12 m/s

Therefore,

K.E=\frac{1}{2}(0.05\ kg)(12\ m/s)^2

K.E = 3.6 J

<h3>b. MAXIMUM GRAVITATIONAL POTENTIAL ENERGY</h3>

First, we will use the third equation of motion to find the maximum height reached by rocket:

2gh=v_f^2-v_i^2

where,

  • g = -9.81 m/s²
  • h = maximum height = ?
  • vf = final speed  = 0 m/s

Therefore,

2(-9.81 m/s²)h = (0 m/s)² - (12 m/s)²

h = 7.34 m

Hence, the maximum gravitational potential energy will be:

P.E = mgh

P.E = (0.05 kg)(9.81 m/s²)(7.34 m)

P.E = 3.6 J

A block of metal which is 20 cm on a side has a mass of 20 kg. What is it’s density? Please answer in MkS (SI) units.
Ratling [72]

The density of an object is given by:

D = M/V

D = density, M = mass, V = volume

The volume of the cube V is given by:

V = s³

where s = side length

Make a substitution:

D = M/s³

Given values:

M = 20kg, s = 20×10⁻²m

Plug in and solve for D:

D = 20/(20×10⁻²)³

D = 2500kg/m³
