A satellite is in circular orbit at an altitude of 2300 km above the surface of a nonrotating asteroid with an orbital speed of 5.9 km/s.
The minimum speed needed to escape from the surface of the asteroid is 14.6 km/s, and G = 6.67 10-11 N m2/kg2. The mass of the asteroid is closest to
A) 1.8 1024 kg.
B) 3.6 1024 kg.
C) 2.7 1024 kg.
D) 8.9 1023 kg.
E) 1.3 1024 kg.
Question 2
A child throws a ball with an initial speed of 8.00 m/s at an angle of 40.0 above the horizontal. The ball leaves her hand 1.00 m above the ground and experience negligible air resistance.
(a) What is the magnitude of the ball's velocity just before it hits the ground?
(b) At what angle below the horizontal does the ball approach the ground?
Parts of the Hand Used in Palpation; Dorsal Surface
The Sun's Surface
The Venusian Surface
Downwelling occurs when surface waters cool, and also when they lose moisture through evaporation. ...
The European Alps have lost ~30% to 40% of surface area and ~50% of volume since the 1850s.
