A 5,000 Kg monster truck is traveling at 11 m/s. when it sees an obstacle it is going to crush during the Monster truck rally, i
avanturin [10]

The change in the kinetic energy of the monster truck during the time is 507500 J and the right option is B). 507500

<h3>What is kinetic energy?</h3>

Kinetic energy is the energy of a body due to its motion.

To calculate the increase in the kinetic energy of the monster truck, we use the formula below.

Formula:

  • ΔK.E = m(v²-u²)/2............. Equation 1

Where:

  • ΔK.E = Increase in kinetic energy of the monster truck
  • m = mass of the monster truck
  • v = final velocity of the monster truck
  • u = initial velocity of the monster truck.

From the question,

Given:

  • m = 5000 kg
  • v = 18 m/s
  • u = 11 m/s.

Substitute these values into equation 1

  • ΔK.E = 5000(18²-11²)/2
  • ΔK.E = 2500(324-121)
  • ΔK.E = 2500(203
  • ΔK.E = 507500 J

Hence, The increase in the kinetic energy of the monster truck during the time is 507500 J and the right option is B). 507500.

A ladybug has a mass of 0.01 g and a velocity of 0.6 m/s. What is his momentum?
Alex

0.000006‬kgm/s

Explanation:

Given parameters:

Mass = 0.01g

Velocity = 0.6m/s

Unknown:

Momentum = ?

Solution:

The momentum of a body is the product of its mass and velocity. It is subject to the impact a body in motion will have .

  Momentum = mass x velocity

The unit is in kgm/s

 We need to convert the mass to kilograms:

       1000g = 1kg

      0.01g = x kg ;  0.00001‬kg

Input the parameter:  

     Momentum = 0.00001 x 0.6 = 0.000006‬kgm/s

Issac and Blaise decide to race. They both start at the same position at the same time. Issac runs at 2m/s but decides to take a
FromTheMoon [43]

Let the Blaise runs for time "t" to complete the race

so the total distance he moved is given by

d_1 = 1* t

Now Issac runs for time t = "t - 2*60"

because it took rest for 2 minutes

d_2 = 2*(t - 120)

now it is given that Blaise wins by 10 m distance

d_1 - d_2 = 10

1* t - 2*(t - 120) = 10

t - 2t + 240 = 10

t = 230 s

now the distance moved by Blaise is given by

d_1 = 1*230 = 230 m

If the speed of a wave doubles while the frequency remains the same, it means
sattari [20]

Answer:

Explanation:

Velocity of a wave is describe as

velocity =Frequency × Wavelength

Mathematically

v = fλ

Hence, Frequency, F = v / λ

Wavelength λ = v/f

So, if the frequency is kept constant, wavelength of the wave becomes directly proportional to velocity of the wave.

And this implies that, as the speed double, the wavelength is double.
