(b)Should the heavier truck go slower than the lighter car ? (c)Find the normal force on each vehicle ( car and truck) due to the highway surface as they round the curve
A bob of mass m is suspended from a fixed point with a massless string of length L (i.e., it is a pendulum). You are to investigate the motion in which the string moves in a cone with half-angle θ. a. What tangential speed, v, must the bob have so that it moves in a horizontal circle with the string always making an angle θ from the vertical? b. How long does it take the bob to make one full revolution (one complete trip around the circle)? Express your answer in terms of some or all of the variables m, L, and θ, as well as the free-fall acceleration g.
e A spaceship of mass m travels from the Earthto the Moon along a line that passes through the center of theEarth and the center of the Moon. (a) At what distance from thecenter of the Earth is the force due to the Earth twice the magnitude of the force due to the Moon? (b) How does your answer topart (a) depend on the mass of the spaceship? Explain
(a) Find the centrifugal acceleration of a particle on the earth’s surface at the equator, due to earth’s rotation, as a fraction of the gravitational field g at that point. (b) Do the same for the centrifugal acceleration due to the motion of earth around the sun. Note that this acceleration is small compared with that due to the axial rotation.
