The ball was thrown horizontally at 10 meters per sec, and the thrower's arm was 78.4 meters above the base of the cliff.

The two balloons are 150-10 = 140 metres apart. They are travelling towards each other at a speed of 15+20 = 35 metres per minute. 140 m at 35 m/minute takes 140/35 = 4 minutes.

At the end of the first day she is (3 - 2) = 1 meter above the bottom.At the end of the second day she is [ 1 + (3 - 2) ] = 2 meters above the bottom.At the end of the third day, she is [ 2 + (3 - 2) ] = 3 meters above the bottom....At the end of the 28th day she is 28 meters above the bottom, assuming she hasn't starved to death yet.During the 29th day, she is in the process of climbing up 3 meters, when she reaches the top and flops outonto the ground. This happens at some time during the 29th day.

Gravitational potential energy = Mass x gravity x heightTherefore, an object at ground level is 0 meters above the ground, thus having no potential energy.PE = mghm = massg = gravitational accelerationh = height

The height of the window above the ground can be calculated using the equation h = (1/2)gt^2, where h is the height, g is the acceleration due to gravity (approximately 9.81 m/s^2), and t is the time taken (2.00 seconds). Plugging in the values, h = (1/2)(9.81)(2)^2 = 19.62 meters. Therefore, the window is 19.62 meters above the ground.

To determine if the stone hits the window, calculate the trajectory of the stone using the vertical and horizontal components of its initial velocity. The time it takes for the stone to reach the window can be found using kinematic equations. If the time is sufficient for the stone to reach the height of the window, then it will hit the window.

It depends on how heigh the window sill is from the ground. it can be right above it, or far from the floor.

If a cat that has a mass of 4.50 kilograms sits on a ledge that is 0.800 meters above ground and it jumps down to the ground, it will have a specific amount of kinetic energy just as it reaches the ground. In this instance, the answer would be 35.3J.

Cirrus clouds typically form at high altitudes, around 20,000 to 40,000 feet (6,000 to 12,000 meters) above the ground.

Using the equations of motion, the height of the window above the ground can be calculated. Assuming the ball falls vertically under gravity, the equation h = (1/2)gt^2 can be used, where g is the acceleration due to gravity (9.8 m/s^2) and t is the time (2.00 seconds). Substituting in the values gives h = (1/2)(9.8 m/s^2)(2.00 s)^2 = 19.6 meters.

The potential energy of a person standing W meters above the ground can be calculated using the formula: Potential energy = mass x gravity x height, where mass is in kilograms, gravity is approximately 9.8 m/s^2, and height is in meters.

The potential energy of an object with respect to the ground can be calculated using the formula PE = mgh, where m is the mass (20 kg), g is the acceleration due to gravity (approximately 9.81 m/s^2), and h is the height above the ground. If the mass is, for example, 2 meters above the ground, the potential energy would be approximately 392.4 J.
