Centripetal Force

A particle, body, object or certain mass while travelling in a rotational path or semicircular path, experiences an inertia force. If that inertia force pulls the towards the inward of the imaginary circle in the rotation, it is termed as centripetal force.

Question

Answer: v_p= 17 723 mi/hr

3/224 Just after launch from the earth, the space-shuttle
orbiter is in the 37 x 137-mi orbit shown. At the
apogee point A, its speed is 17,290 mi/hr. If nothing
were done to modify the orbit, what would its speed
be at the perigee P? Neglect aerodynamic drag.
(Note that the normal practice is to add speed at A,
which raises the perigee altitude to a value that is
well above the bulk of the atmosphere.)

(a) Calculate the work (in MJ) necessary to bring a 104 kg object to a height of 991 km above the surface of the Earth. -854 X The work done must provide the increase in gravitational potential energy, so calculate AU, for the system. You will need the radius and mass of the Earth for your calculation. MJ (b) Calculate the extra work (in J) needed to launch the object into circular orbit at this height. 2.619E9 X Notice that the centripetal force for the object in orbit is due to the gravitational force from the Earth. Write and equate two expressions for the force, in terms of Newton's universal law of gravitation and the centripetal force, and solve for v2. The additional work is equal to the kinetic energy, so find K using your value for v². J
