Problem (8):

Physics
1 answer:

Answer:

<em>x=6 m, y= 3 m</em>

Explanation:

<u>Projectile Motion</u>

It's the type of motion that experiences an object launched near the Earth's surface and moves along a curved path under the action of gravity.

Being vo the initial speed of the object, θ the initial launch angle, and g the acceleration of gravity, then the components of the velocity at a given time t are:

v_x=v_o\cos\theta

v_y=v_o\sin\theta-g.t

And the components of the displacement are:

x=v_o\cos\theta .t

\displaystyle y=v_o\sin\theta.t-\frac{g.t^2}{2}

The projectile of the problem is fired at θ=53° with an initial speed of vo=10 m/s.

Thus, after 1 second, the components of the displacement are:

x=10\cos 53^\circ \cdot 1

x\approx 6~m

\displaystyle y=10\sin 53^\circ\cdot 1-\frac{9.8\cdot 1^2}{2}

y\approx3~m

Answer: x=6 m, y= 3 m

None of the options match this answer.

An 11.0 -W energy-efficient fluorescent lightbulb is designed to produce the same illumination as a conventional 40.0-W incandes
yarga [219]

The amount or cost that the user of the energy-efficient bulb save during 100h of use will be $0.319.

<h3>How to calculate the cost?</h3>

For the 11.0W bulb, it should be noted that the value will be:

= 11.0 × 100 × (1/1000) × 0.110

= $0.121

The 40W bulb will be:

= 40 × 100 × (1/1000) × 0.110

= $0.44

Therefore, the amount that will be saved will be:

= $0.44 - $0.121

= $0.319
