A golf ball was smashed at 25ms^-1 and at a angle of 40 degrees
a) find the total time it took for the ball to bounce (2 marks)
b) find range (2 marks)
The ratio is just 1:1:1 as orbital radii --> identical for all three moons (since the orbital speed and orbital does not depend on the mass).
When Fc = Fg
where Fc = (mv^2)/2 -------- and Fg = (GmMp)/r^2 )where Mp is the mass of the planet)
ending up with r = (GMp)v^2 (masses cancel...
Determine the gravitational force between a 77.5 kg astronaut and Earth when he is standing on the ground. Calculate the change in gravitational force when the astronaut is inside a satellite orbiting the Earth at an altitude of 685 km. The radius of the Earth is 6380 km and the mass of the...
Did few questions
1. D
2. B
3. A
4. C
5. A
6. D
Not sure about 6
Hope the rest are correct
For 11b I got
[(2/5)(x-4)^5/2]+[(8/3)(x-4)^3/2]+C
11e
x<-3 or -5/2 < x < 1/2
Hope they're correct
