The force required to produce the centripetal component of acceleration is called the centripetal force and is given by F = mv2/r. Newton's Law of Universal Gravitation is given by F = GMm/d2, where d is the distance between the centers of the two bodies of masses M and m, and G is a gravitational constant. The speed required for circular motion is v = √ GM/r. Use the result above to find the speed necessary for the given circular orbit around Earth. Let GM = 9.56 x 104 cubic miles per second per second, and assume the radius of Earth is 4000 miles. (Round your answer to two decimal places.) The orbit of a communications satellite R miles above the surface of Earth that is in geosynchronous orbit. [The satellite completes one orbit per side real day (approximately 23 hours, 56 minutes), and therefore appears to remain stationary above a point on Earth.] X mi/sarrow_forwardAn object is shot straight upward from sea level with an initial velocity of 400 ft/sec. a. Assuming that gravity is the only force acting on the object, give an upper estimate for its velocity after 5 sec have elapsed. Use g = 32 ft/sec2 for the gravitational acceleration. b. Find a lower estimate for the height attained after 5 sec.arrow_forward
- A firework of mass 0.4 kg is fired vertically upwards with initial speed 40 m/s. The firework itself provides a force of 2 N upwards. The firework explodes after 6s. Find the height at which it explodes.arrow_forwardA 60-kg woman holds a 9-kg package as she stands within an elevator which briefly accelerates downward at a rate of a = 3.1 m/s². Determine the force N which the elevator floor exerts on her feet and the lifting force L which she exerts on the package during the acceleration interval. If the elevator support cables suddenly and completely fail, what values would N and L acquire? (N = 463 N, L = 60.4 N, N = L = 0) 9 kg a 60 kgarrow_forwardA mass weighing 20 pounds stretches a spring 6 inches. The mass is initially released from rest from a point 8 inches below the equilibrium position. (a) Find the position x of the mass at the times t = ?/12, ?/8, ?/6, ?/4, and 9?/32 s. (Use g = 32 ft/s2 for the acceleration due to gravity.)arrow_forward
- A sheet of water of uniform thickness (h = 0.03 m) flows from the device shown in the figure below. The water enters vertically through the inlet pipe and exits horizontally with a speed that varies linearly from 0 to 11 m/s along the 0.2-m length of the slit. Determine the y component of anchoring force necessary to hold this device stationary.

The electron strikes the screen after traveling 17.0 cm horizontally and 40.0 cm vertically upward with no horizontal acceleration. What is the constant vertical acceleration provided by the deflector? (The effects of gravity can be ignored.) 1.4 x 10 m/s? 14 2.5 x 10 m/s2 14 1.2 x 10 m/s? 8.3 x 10 m/s?arrow_forward
