Answer:

<h2>3000 J</h2>

Explanation:

The kinetic energy of an object can be found by using the formula

k =  \frac{1}{2} m {v}^{2}  \\

m is the mass in kg

v is the velocity in m/s

From the question

m = 60 kg

v = 10 m/s

We have

k =  \frac{1}{2}  \times 60 \times  {10}^{2}  \\  = 30 \times 100 \\  = 3000

We have the final answer as

<h3>3000 J</h3>

Hope this helps you

Answer:

\boxed {\boxed {\sf 3000 \ J}}

Explanation:

Kinetic energy is the energy an object has due to motion. It is calculated using the following formula:

KE=\frac{1}{2} mv^2

The mass of the go-cart is 60 kilograms and the velocity is 10 meters per second.

  • m= 60 kg
  • v= 10 m/s

Substitute the values into the formula.

KE= \frac{1}{2} (60 \ kg)(10 \ m/s)^2

Solve the exponent.

  • (10 m/s)² = 10 m/s * 10 m/s = 100 m²/s²

KE = \frac{ 1}{2} (60 \ kg)(100 \ m^2/s^2)

Multiply the numbers together.

KE= 30 \ kg * 100 \ m^2/s^2

KE= 3000 \ kg*m^2/s^2

Convert the units. 1 kilogram meter squared per second squared is equal to 1 Joule, so our answer of 3000 kg*m²/s² equals 3000 Joules.

KE= 3000 \ J

The go-cart has <u>3000 Joules</u> of kinetic energy.

Andrej [43]

Answer:

work done will be equal to 305.05 J

Explanation:

We have given force exerted F = 45 N

Angle with the horizontal \Theta =41^{\circ}

Distance moved due to exerted force d = 9.1 m

Work done is equal to W=Fcos\Theta \times d , here F is force \Theta is angle with horizontal and d is distance moved due to force

So work done W=45\times cos41^{\circ}\times 9.1=309.05J

So work done will be equal to 305.05 J

A 25-cm rod moves at 5. 0 m/s in a plane perpendicular to a magnetic field of strength 0. 25 t. the rod, velocity vector, and ma
Bad White [126]

Length L = 25 cm = 0.25 m,  B = 600 G =  0.06 T ( 1G = 0.0001 T)

emf= 10 V

Solution:

emf = vBL

v= emf / BL

5 = emf/ (0.25 T× 0.25 m)

emf = 0.3125 v

Magnetic field

The magnetic influence on moving electric charges, electric currents, and magnetic materials is described by a magnetic field, which is a vector field. A force perpendicular to the charge's own velocity and the magnetic field acts on it when the charge is travelling through a magnetic field.
