A ball is dropped from rest from the top of a building of height h. At the same instant, a second ball is projected vertically upward from ground level, such that it has zero speed when it reaches the top of the building. a) When do the two balls pass each other? Answer it in terms of h. b)Which ball has greater speed when they are passing? c)What is the height of the two balls when they are passing?

1. A square-based pyramid has the volume V. If the vertical height is H (the normal distance from the square base to the point), write a MATLAB function that: has V and H as input arguments calculates the length of the side of the square (S) has S as an output argument Write MATLAB code that tests the function for the values: V = 10 m3 and H = 2 m. V = 2.586×106 m3 and H = 146.6 m...

A roller-coaster car is starting from rest from the top of the slope of height H. As it reaches the bottom of the slope, it is moving at 30 m/s along a straight horizontal track. Using the principle of conservation of energy, a. Calculate the height H. b. Calculate the speed of the roller-coaster car after climbing the 10 m hill shown in the figure. Ignore friction. c. What is the change in kinetic energy as the car goes a....

If dropped together from a height h, how high does a tennis ball on top of a basketball bounce (tennis ball’s mass is much smaller than basketball’s mass) ? (please explain this in steps with very in depth explaination, i am dumb lol please explain like you are explaining to a little kid. do not write in cursive)

A page is to have a total area of 96 square inches. The top and bottom margins will be 1 inch each, and the left and right margins will be 11⁄2 inches each as shown in the figure below. Required: a) What should be the overall dimensions “x” and “y” that will maximize the area of the space inside the margins (the printed area)? b) Also give the proof that these values of “x” and “y” will maximize this area.

Say you have a bottle of water filled up to a height H. A small hole is drilled in its side at a height d, so that water squirts out. The squirting water travels in an arc as it falls, covering some horizontal distance S away from the bottle before it hits the table top that the bottle sits on. Multi-part question to try to understand this completely: At what height d should the hole be placed so that its...

Three jars each have volume V and height h, but they have different shapes as shown in (Figure 1) . Water is to be added to each jar and the pressure is to be measured right at the bottom of each jar. Figure 1 Part A Rank the jars in order of decreasing pressure if the volume of water is V. Rank from largest to smallest. To rank items as equivalent, overlap them. Pa, Pc , Pb or correct ranking...

A water tank consists of a cylindrical part of radius r and height h and a hemispherical top. The tank is to be constructed to hold 600 m3

A water tank consists of a cylindrical part of radius r and height h and a hemispherical top. The tank is to be constructed to hold 600 m3 when filled. The surface area of the cylindrical part is 2πrh, and its volume is πr2h. The surface area of the hemispherical top is given by 2πr2, and its volume is given by 2πr3/3. The cost to construct the cylindrical part of the tank is $400 per square meter of surface area;...
