Flight to Mars. To send a satellite from Earth to Mars, a rocket must accelerate the satellite until it is in the correct elliptical orbit around the sun. The satellite does not travel to Mars under rocket power, because that would require more fuel than it could carry. It just moves on a Keplerian orbit under the influence of the sun's gravity. The satellite orbit must have perihelion r = 1.496e11 meters, and aphelion r = 2.28e11 meters.
Calculate the time for the satellite's journey. Express the result in days.
A 0.13 kg baseball is hit by a .95 kg bat. The contact point on the bat is moving at 40 m/s just prior to ballbat contact, How fast is the ball moving just after impact
The force on a particle is directed along an x axis and given by F = 0.97(x/4.6 - 0.52) where x is in meters and F is in Newtons. Find out the work done by the force in moving the particle from x = 0 to x = 8.9 m.
A bullet is shot from a gun to demonstrate projectile motion. The initial velocity v0 of the bullet is 64 m/s and it starts at an angle of 52° above the ground. determine the maximum height the bullet can reach
A small turtle moves at a speed of 165 furlongs per fortnight. Find out the speed of the turtle in centimeters per second. Note that 1 furlong = 220 yards and 1 fortnight = 14 days.
On a winter day heat leaks out of a house at the rate of 2.5x10^4 kcal/h. At what rate does this process produce entropy
Why is you are not harmed with the contact of a charged metal ball, although its voltage may be very high? Is the reason similar to why you are not harmed by greater-than-10000 C sparks from the Fourth-of-July sparkler? Define your answer in terms..
An infinitely long line of charge has a linear charge density of 5.00×10^?12 C/m. A proton is at distance 12.0 cm from the line and is moving directly toward the line with speed 1500 m/s. How close does the proton get to the line of charge?
What would be the electric current intercepted by the total surface area of the planet?
