A bowling ball has a mass of 6 kilograms. A person lifts the bowling ball 2 meters above the ground, using a force of about 60
Luba_88 [7]

The amount of work done by the person is equal to 120 Joules.

<u>Given the following data:</u>

  • Force = 34 Newton.
  • Displacement = 15 meters.
  • Mass = 6 kilograms.

To calculate the amount of work done by the person at a total height of 2 meters:

<h3>How to calculate work done.</h3>

In Science, work done is calculated by multiplying force and the displacement experienced by an object.

Mathematically, work done is given by the formula:

Work\;done = force \times displacement

Substituting the given parameters into the formula, we have;

Work\;done = 60 \times 2

Work done = 120 Joules.

The three vectors in Fig. 3-33 have magnitudes a = 3.00 m, b = 4.00 m, and c = 10.0 m and angle θ = 30.0°. What are
aliya0001 [1]

Answer:

a) a_{x} =3              b) a_{y} =0

c) b_{x} =3.46        d) b_{y} =2

e) c_{x} =0              f) c_{y} =10

g) p = -5.77                            h) q=5

Explanation:

Diagram for given question is attached below in fig 1

<h3>Part (a) (b)</h3>

for vector \vec{a}

θ = 0°

          a_{x} = 3 cos (0)\\a_{x} = 3\\a_{y} = 3 sin (0)\\a_{y} = 0

<h3>Part (c) (d)</h3>

for vector \vec{b}

θ = 30°

      b_{x} = 4 cos (30)\\b_{x} = 3.46\\b_{y} = 4 sin (30)\\b_{y} = 2

<h3>Part (e) (f)</h3>

for vector \vec{c}

θ = 90°

    c_{x} = 10 cos (90)\\c_{x} = 0\\c_{y} = 10 sin (90)\\c_{y} = 10

<h3>Part (g) (h)</h3>

                       \vec{c} = p\vec{a} + q\vec{b}

c =c_{x} \hat{i} + c_{y}\hat{j}\\as a_{y} =0\\c_{x} \hat{i} + c_{y}\hat{j} = pa_{x} \hat{i} +q(b_{x} \hat{i}  +b_{y} \hat{j} )\\c_{x} \hat{i}  = pa_{x} \hat{i} +qb_{x} \hat{i}\\c_{y}\hat{j}  =qb_{y}\hat{j}

                  q=\frac{c_{y}}{b_{y}} \\q=\frac{10}{2}\\q=5

c_{x} \hat{i}  = pa_{x} \hat{i} +qb_{x} \hat{i}\\0 = p(3) + (5)(3.46)\\p = -5.77
