Concept explainers
Referring to Conceptual Example 10-17 Suppose we race a disk and a hollow spherical shell, like a basketball. The spherical shell has a mass M and a radius R; the disk has a mass 2M and a radius 2R. (a) Which object wins the race? If the two objects are released at rest, and the height of the ramp is h = 0.75 m, find the speed of (b) the disk and (c) the spherical shell when they reach the bottom of the ramp.

(a) Assuming the particle moves at a constant speed, show that F = mg cos . Note: If the particle moves at constant speed, the component of its acceleration tangent to the cylinder must be zero at all times. (b) By directly integrating W=Fdr, find the work done in moving the particle at constant speed from the bottom to the top of the hall-cylinder. Figure P7.15arrow_forward

You can assume that the radius of the ball is negligible. a. h = 1.35 m, = 25, and m = 0.65 kg b. R = 33.5 m and m = 756 kg c.

- PRO BLEM 10: A PARTICLE IN A PARABOLIC BOWL := kr Suppose a particle of mass m lives inside a parabolic bowl. The height z of the bowl is given, as a function of it's radius as z = kr², where k is a number. On a particular day the particle finds itself at a height zo as measured from the bottom of the parabola. At that instant it has a horizontal speed vo. Ignoring friction calculate (1) for a given value of horizontal velocity, that is we will let vo → Vh, the particle will move in a perfect circle. What is this v,? Answer this part of the question by drawing a free body diagram and applying New ton's laws. (2) Now, suppose vo > vh, where, vh is the value you calculated above. What is the maximum height reached by the particle? Answer this part of the question by evoking the conservation of energy, and remember to discuss what happens to angular momentum here. (3) Now, suppose vo = 0, but the particle is still at 20. Let us assume that 20 is small and that he particle will undergo…arrow_forwardA team of astronauts is on a mission to land on and explore a large asteroid. In addition to collecting samples and performing experiments, one of their tasks is to demonstrate the concept of the escape speed by throwing rocks straight up at various initial speeds. With what minimum initial speed vesc will the rocks need to be thrown in order for them never to "fall" back to the asteroid? Assume that the asteroid is approximately spherical, with an average density p 3.06 x 106 g/m³ and volume V = 3.32 x 1012 m³.

Consider the mechanical energy of the same body on Earth at the South pole, at re=6400 km. For this problem, we consider the Earth to be spherical. (Remember, the object at the equator is in orbit, the object at the Pole is not in orbit.)

Assume that the planet does not move or spin, so that the total mechanical energy E of a test particle both on the surface and at infinity is equal to zero, and the speed at infinity is zero. Use the formula come up in the last part, Compute this escape speed (in km/s) from Venus, Mars, Jupiter and Neptune. b) Evaluate vIII from the heliocentric orbit of the 4 planets (Venus, Mars, Jupiter and Neptune) mentioned above, assuming circularity of their orbits. Compare the computed speeds with the escape speeds from their surfaces (vII). Notice a big difference in the situation around the inner and the outer planets. What is it due to? A fly-by’s of small bodies near a planet can result in the small particle being accelerated to a final speed close to vII w.r.t. the planet.
