A:
A space vehicle is to rendezvous with an orbiting laboratory that circles the earth at a constant altitude of 360 km. The vehicle has reached an altitude of 60 km when its engine is shut off, and its velocity v0 forms an angle φ0 = 50° with the vertical OB at that time. What magnitude should v0 have if the vehicle’s trajectory is to be tangent at A to the orbit of the laboratory?

- An object rolls off a tabletop with a horizontal velocity v0x = 18 m/s. The table is at a height y0 = 0.75 m, above the floor. Use a coordinate system with its origin on the floor directly beneath the point where the object rolls off the table, its horizontal x-axis lying directly beneath the object’s trajectory, and its vertical y-axis pointing up. What is the magnitude of the velocity (its speed) when it hits the floor?A carnival merry-go-round rotates about a vertical axis at a constant rate.

It makes a gradual 180° turn (at any instant, the turning angle is less than 90°) at constant speed of 415.5 km/h, changing its direction of travel from north through east to south in 36.5 s. The centripetal acceleration of the plane for this turn in m/s2 is: Answer: The force of gravitational attraction hetween tuuo nhinntamith
- The earth rotates once per day about an axis passing through the north and south poles, an axis that is perpendicular to the plane of the equator. Assuming the earth is a sphere with a radius of 6.38 x 10 m, determine the speed and centripetal acceleration of a person situated (a) at the equator and (b) at a latitude of 65.0 ° north of the equatorIn my homework, I am asked to derive an equation for V0. The homework question is as follows: A howitzer fires a shell with a velocity of v0 at an angle Θ above the horizontal. The howitzer is on a plateau and the shell lands down in the plain below, a vertical distance d below the plateau and a horizontal distance L from where the howitzer is. Derive an expression for the magnitude of the initial velocity, V0, as a function of d, L, g, and Θ. Any help would be appreciated as I have worked on this problem for quite a while and I am not making progress.An Earth satellite moves in a circular orbit 687 km above Earth's surface with a period of 98.30 min. What are (a) the speed and (b) the magnitude of the centripetal acceleration of the satellite?
