The moom revolves around earth every 27.3 days and is 390000 km from the center. How long would it take a satellite launched to a distance of 6700 km from the center of the earth to orbit the earth

it is 88.5 minutes

What is the gravitational force between a mass of 20 kg and a mass of 100 kg that are 15 meters apart

5.9 x 10^-10 N

An isolated system is one which is not subject to any forces

A bicycle is an example of what machine

A bicycle is an example of a complex machine, consisting of interacting simple machines.

The value of the impulse equals the force x the

The value of the impulse equals the the force times the time.

A player kicks a soccer ball from ground level and sends it flying at an angle of 30 degrees at a speed of 26 ms What is the maximum height attained by the ball

10.7

V-cube 7 or megaminx

The momentum of two objects before collision is the same as the momentum of the two objects after collision

Yes. The total momentum would be the same. This is an example of the conservation of linear momentum.

17.8 m/s

A golfer tees off and hits a golf ball at a speed of 31 ms and at an angle of 35 degrees what is the horizontal velocity component of the ball

25.4

A ball is thrown horizontally from a cliff at a speed of 15 ms and strikes the ground 45 meters from the base of the cliff How high was the cliff rounded to the nearest meter

Answer: 44 meters

A+ Answers

A golfer tees off and hits a golf ball at a speed of 31 ms and at an angle of 35 degrees How far did the ball travel before hitting the ground Round the answer to the nearest tenth of a meter

92 or 91.5 meters would be the maximum height.

A golfer tees off and hits a golf ball at a speed of 31 ms and at an angle of 35 degrees How long was the ball in the air Round the answer to the nearest tenth of a second

3.6

A golfer tees off and hits a golf ball at a speed of 31 ms and at an angle of 35 degrees What is the maximum height attained by the ball Round the answer to the nearest meter

16 or 16.1 meters is the maximum height.

A player kicks a soccer ball from ground level and sends it flying at an angle of 30 degrees at a speed of 26 ms

Yes your question is.......................

A Ball Is Thrown Horizontally At 20 Ms From The Top Of A Cliff 50 Meters High How Far From The Base Of The Cliff Does The Ball Strike The Ground

the time it takes to get to ground is s = 1/2 at^2 where a is gravity acceleration of 9.8 m/s/s and s is 50 meters and t^2 is time squared.Solve for time t = 3.2 secondsThe horizontal distance from base of cliff is h = vt where h is distance and v is velocity = 20 m/sh = 20 x 3.2 = 64 meters

A golfer tees off and hits a golf ball at a speed of 31 ms and at an angle of 35 degrees. What is the vertical velocity component of the ball Round the answer to the nearest tenth of a ms.
