A projectile is launched directly upward from the surface of the Earth with an initial speed of 5.1 km/s. Assuming air resistance is negligible, what is the maximum height of the projectile (in m)? x GM₁M₂ The height attained is not small compared to the radius of the Earth, so U = mgy does not apply; so you need to use U = - in your conservation of mechanical energy equation. m

- A box is shoved up a frictionless incline with an initial speed of 13 m/s. The inclined plane makes an angle of 35 degrees with respect to the horizontal. The length of the incline is 60 m. How far above the ground Is the box when it comes to rest? Options for answers: a. 12.3 m b. 8.6 m c. 15.1 m d. 10.5 mJust before entering the tunnel, you notice the sign that says you must "use the tunnel with your bicycle on foot" but it is too late and you are descending through the tunnel with an initial speed of 6.6 km / h. The tunnel has a semicircular ramp with radius R = 6.3 m, and its mass combined with the mass of the bicycle is 60.3 kg. a) Find the velocity at the bottom of the curve, point 2, for when the friction force is negligible.In a truck-loading station at a post office, a small 0.200 kg package is released from rest at point A on a track that is one-quarter of a circle with radius 1.60 m. The size of the package is much less than 1.60 m, so the package can be treated as a particle. It slides down the track and reaches point B with a speed of 4.80 m/s. From point B, it slides on a level surface a distance of 3.00 m to point C, where it comes to rest. (a) What is the coefficient of kinetic friction on the horizontal surface? (b) How much work is done on the package by friction as it slides down the circular arc from A to B?
- A student is on the roof of the SP building, 15.0 m above the ground. Your physics instructor, who is 163 cm tall, is walking alongside the building at a constant speed of 0.35 m/s. If you wish to drop an egg on your instructors head, where should the instructor be when you release the egg? Assume the egg is in free fall and air friction is “negligible”.Consider the observation that the acceleration due to the gravitational force acting on a mass around a host planet decreases with the square of the separation between the objects. We can ask ourselves: why is it still accurate to consider a gravitational acceleration value of 9.8\frac{m}{s^2}9.8s2m for all of our projectile motion problems and all of our gravitational potential energy from prior modules? Let's analyze a situation and justify this analysis method: consider an object being launched from ground level to an altitude of 10,000 meters, roughly the cruising altitude of most jet liners, and far above our everyday experiences on Earth's surface. Compare the gravitational acceleration of the object at Earth's surface (the radius of Earth is about r_E=6.37\times10^6mrE=6.37×106m) to the acceleration value at the 10,000 meter altitude by determining the following ratio: g10,000m/gsurface3.64 A 2.7-kg ball is thrown upward with an initial speed of 20.0 m/sm/s from the edge of a 45.0 mm high cliff. At the instant the ball is thrown, a woman starts running away from the base of the cliff with a constant speed of 6.00 m/sm/s. The woman runs in a straight line on level ground, and air resistance acting on the ball can be ignored. 1. At what angle above the horizontal should the ball be thrown so that the runner will catch it just before it hits the ground?
- The work required to accelerate an object on a frictionless surface from speed v to 2v is a. You cannot know without knowledge of acceleration. b. Four times the work required to accelerate the object from 2v to 3v. c. Three times the work required to accelerate the object from v=0 to v. d. Equal to the work required to accelerate the object from v=0 to v. e. Twice the work required to accelerate the object from v=0 to v.An 8.00 kg block of ice is released from rest at the top of a 1.50 m long friction less ramp and reaches a speed of 2.50 m/s at the bottom. What is the angle between the ramp and the horizontal? 12.3 degrees 13.3 degrees 14.3 degrees 15.3The figure below shows a motorcycle leaving the end of a ramp with a speed of 39.6 m/s and following the curved path shown. At the peak of the path, a maximum height h above the top of the ramp, the motorcycle's speed is 37.7 m/s. What is the maximum height h? Ignore friction and air resistance. (Enter your answer in m.)
- A small sphere of mass m is launched horizontally over a body of water from a height h above the water and with a launch speed v0. Determine expressions for the following in terms of m, v0, h, and g. Air resistance is negligibly small. (a) W is the amount work done by the force of gravity on the projectile during its flight. (b) ΔKE is the change in kinetic energy ΔKE of the projectile from the time it was fired until it hits the water. (c) KEf is the final kinetic energy KEf of the projectile as it hits the water.A skater with mass 65 kg is skating on a horizontal surface at a constant speed. There is a ramp ahead, and the skater has just enough speed to make it to the top of the ramp (meaning the speed at the top of the ramp is 0 m/s). The height of the ramp is 1.9 m. Answer the following 5 questions. In this problem, set the reference point of the height at the horizontal surface, and use g = 9.8 m/s2 for the acceleration due to gravity. Ignore air resistance and friction unless otherwise stated. At the top of the ramp, Person A pushes the skater down the ramp. When the skater goes down to the horizontal surface, he is moving at the speed of 9.2 m/s. What is the work done by Person A on the skater during the push? There is another ramp of the height 2.5 m. What is the speed of the skater at the top of this ramp?A skater with mass 65 kg is skating on a horizontal surface at a constant speed.
