Read the scenario below and answer the question that follows. Randall is hiring cooks for his restaurant. The first applicant is

a handsome man with an average resumé and average job experience. The second applicant is a far less attractive man with a slightly above average resumé and above average job experience. Randall decides to hire the first applicant. Based on this information and on Randall’s decision, what might a psychologist conclude about Randall’s social perception? Randall has an unconscious assumption that attractive people are more competent. Randall has a unconscious assumption that unattractive people are bad cooks. Randall has a conscious assumption that attractive people make better cooks. Randall has a conscious assumption that unattractive people are more competent.

Answer:

The maximum height that a cannonball fired at 420 m/s at a 53.0° angles is 5740.48m.

hmax = 5740.48 m

Explanation:

This is an example of parabolic launch. A cannonball is fired on flat ground at 420 m/s at a 53.0° angle and we have to calculate the maximum height that it reach.

V₀ = 420m/s and θ₀ = 53.0°

So, when the cannonball is fired it has horizontal and vertical components:

V₀ₓ = V₀ cos θ₀ = (420m/s)(cos 53°) = 252.76 m/s

V₀y = V₀ cos θ₀ = (420m/s)(cos 53°) = 335.43m/s

When the cannoball reach the maximum height the vertical velocity component is zero, that happens in a tₐ time:

Vy = V₀y - g tₐ = 0

tₐ = V₀y/g

tₐ = (335.43m/s)/(9.8m/s²) = 34.23s

Then, the maximum height is reached in the instant tₐ = 34.23s:

h = V₀y tₐ - 1/2g tₐ²

hmax = (335.43m/s)(34.23s)-1/2(9.8m/s²)(34.23s)²

hmax = 11481.77m - 5741.29m

hmax = 5740.48m

Lauryn serves a volleyball with a mass of 2.1 kg. The ball leaves her hand with a speed of 30 m/s.

Hi! Let's see.

<h3><u>TOPIC: Kinetic Energy.</u></h3>

Explanation:

Data:

  • Mass(m) = 2.1 kilograms
  • Speed(v) = 30 m/s
  • Kinetic Energy(Ek) = ?

==================================================================

Use the kinetic energy formula:

  • \boxed{\boxed{\bold{E_{k}=\frac{m*(v)^{2}}{2}}}}

Replace by the data:

  • \boxed{E_{k}=\frac{2.1kg*(30\frac{m}{s})^{2}}{2}}}}}

We multiply speed squared:

  • \boxed{E_{k}=\frac{2.1kg*900\frac{m}{s}}{2}}}

Multiply in the numerator, without forgetting the units:

  • \boxed{E_{k}=\frac{1890J}{2}}}}

Both numerator and denominador operations are divided:

  • \boxed{\bold{E_{k}=945\ J}}

Answer: The kinetic energy is <u>945 Joules.</u>
