Answer:
is possibly approximate, as maximum height attained may have been over the top of the net, i.e. small error in horizontal V component. Or maybe comes from the "about" 1.15 secs. in air.
Explanation:
2.3 + 0.95) = 3.25 metres.
Angle of hit = arctan (3.25/11.3) = 16.046 degrees above horizontal.
The ball was 1.15 secs. in the air, so reached max. height in (1.15/2) = 0.575 sec.
Height attained over court = 1/2 (t^2 *g) = 1.62 metres.
Initial vertical V component = sqrt.(2gh) = sqrt.(19.6 x1.62) = 5.6349m/sec.
Range = (4h/tan 16.046) = (1.62 x 4)/tan 16.046 = 22.53 metres.
Horizontal V component = (22.53/1.15s) = 19.59m/sec.
Speed of hit = sqrt.(19.59^2 + 5.6349^2) = 20.384m/sec.
Answer:
Faster
Explanation:
The closer the particles are together, the faster sound is able to move.
Sound travels the slowest through the air because gas particles are more spread apart than liquids or solids.
Sound will travel the fastest through solids because the particles in solids are densely packed together.
It depends on the type of clay because there are some clays that are artificial
There was no net force on the stuffed toy, because the kids might have the same strength, The same force is on both sides of it. T<span>hey cancel each other out. They exert a force on the stuffed toy equal in strength but opposite in direction. The forces are balanced and the stuffed toy does not move. </span>Its like a game of tug-o-war, but you and I have the same strength. the rope would be still and not moving.
The magnetic properties of the ball help to travel in the pin ball.
<h3>What is pinball?</h3>
A Pinball is a steel sphere of diameter 3 cm. It weighs 2.8 ounces. The ball can reach speed upto 90 miles per hour on the traditional steel pinball.
The magnetic properties of the ball help to travel in the pinball , as some machines uses the magnets to trap the ball in certain places on the playfield.
In some of the machines the ceramic pinball is called Powerball.
Pinball move around the table, hitting bumpers and some targets to score the points.
You'll get only three balls to play, when your third ball falls down then your game will be over.
So, the ball in the pinball will travel because of then magnetic properties of ball.
