\large{{\bold{ \underline{ \underline{ \overline{ \overline{ \red{☆Solution :—}}}}}}}}

↪Total energy = 750 J

↪Efficiency = 50%

↪Wasted energy = 50% [ 100% - 50%]

<u>Amount of wasted energy</u>

↦ 750 x 50%

↦ 750 x 0.5

↦ 375 J

Answer:

<u><em>375 J</em></u>

Explanation:

<u><em>Total energy</em></u> = 750 J

<u><em>Efficiency</em></u> = 50%

<u><em>Wasted energy</em></u> = 50% [100% - 50%]

<u><em>Amount of wasted energy</em></u>

= 750 x 50%

= 750 x 0.5

= 375 J

A baseball player friend of yours wants to determine his pitching speed. you have him stand on a ledge and throw the ball horizo
zhenek [66]

Answer:

The pitching speed of your friend is 33.20 m/s

Explanation:

<em>Lets explain how to solve the problem</em>

Your friend throw the ball horizontally that means the vertical initial

component of velocity is zero (u_{y}=0).

The ball is thrown from a height 4 meters above the ground.

The height h=u_{y}t+\frac{1}{2}gt^{2}

<u><em>Remember:</em></u> the height is negative value because its below the point of

thrown (initial position)

h = -4 m , u_{y}=0 and g = -9.8 m/s²(downward)

<em>Substitute these values in the rule above</em>

⇒ 4=0-\frac{1}{2}(9.8)t^{2}

⇒ -4 = -4.9t² (multiply both sides by -1)

⇒ 4 = 4.9t² (divide both sides by 4.9)

⇒ 0.81633 = t² (take √ for both sides)

⇒ <em>t = 0.9035</em>

Then the time of the ball to land on the ground is 0.9035 seconds

The range of the ball on the ground is 30 m

The range R=u_{x}*t, where u_{x} is the horizontal

component of the initial velocity

R = 30 meters and t = 0.9035

⇒ 30=u_{x}(0.9035) (divide both sides by 0.9035)

⇒ u_{x}=33.20 m/s

<em>The pitching speed of your friend is 33.20 m/s </em>
