Suppose Sammy Sosa hits a home run which travels 361. ft (110. m). Leaving the bat at 50 degrees above the horizontal, how high
Mashcka [7]

Answer:

The horizontal distance of Sosa is 276.526 ft or 84.28 meter.

Explanation:

As shown in the figure, let point O is the starting point of Sosa. She travels 361 ft at an angle 50 degree with the horizontal.

sin 50 = \frac{OM}{OP}

0.7660 = h / 361

h = 276.526 ft

h = 84.28 meter

The horizontal distance of Sosa is 276.526 ft or 84.28 meter.

Kendra lifts a box using a force of 80 N. She lifts the box a height of 0.5
Fynjy0 [20]

The work she on the box will be 40 J. Here the displacement due to the force is height.

<h2 /><h3>What is work done?</h3>

Work done is defined as the product of applied force and the distance through which the body is displaced on which the force is applied.

Given data;

Force,F = 80 N

height, h = 0.5 m

Work,W = ? J

Here the displacement is height;

W  = F × d

W = F × h

W = 80 N ×  0.5 m

W = 40 Nm

W=40 J

Hence work she on the box will be 40 J.

To learn more about the work done refer to the link;
