One of the limiting factors in high-performance aircraft is the acceleration to which the pilot can be subjected without blacking out; it’s measured in “gees,” or multiples of the gravitational acceleration. The F-22 Raptor fighter can achieve Mach 1.8 (1.8 times the speed of sound, which is about 340 m/s). Suppose a pilot dives in a circle and pulls up. If the pilot can’t exceed 6g, what’s the tightest circle (smallest radius) in which the plane can turn?

- In a classic clip on Americas Funniest Home Videos, a sleeping cat rolls gently off the top of a warm TV set. Ignoring air resistance, calculate the position and velocity of the cat after (a) 0.100 s, (b) 0.200 s, and (c) 0.300 s.arrow_forwardThe acceleration due to gravity of a particle falling toward the earth is a=-gR2/r2, where r is the distance from the center of the earth to the particle, R is the radius of the earth, and g is the acceleration due to gravity at the surface of the earth. If R = 3960 mi, calculate the escape velocity, that is, the minimum velocity with which a particle must be projected vertically upward from the surface of the earth if it is not to return to the earth. (Hint: v = 0 for r= ∞.)arrow_forwardA person swings a rock around on a string, causing it to sweep out in a circle of radius 1.8 m. If the rock travels at a constant speed of 18.7 m/s, what acceleration does it experience?arrow_forward
- lo, a satellite of Jupiter, is the most volcanically active moon or planet in the solar system. It has volcanoes that send plumes of matter over 500 km high. Due to the satellite's small mass, the acceleration due to gravity on lo is only 1.81 m/s², and lo has no appreciable atmosphere. Assume that there is no variation in gravity over the distance traveled ▼ What must be the speed of material just as it leaves the volcano altitude of 310 km?

If the gravitational potential energy is zero at the surface, what is the potential energy for a 35 kg fragment at its maximum height (500 km) on lo? Express your answer in joules.

Assuming it doesn’t reach the ground, after 4 seconds its speed will be aboutarrow_forwardA 17 kg car travels in a flat circle. At a certain instant, the velocity of the car is 18 m/s west and the total acceleration of the car is 2 m/s2 at 51 degrees north-west. What is its radius? Answer in units of km.arrow_forward
- You have put a sonar device at the top of a frictionless inclined plane. That device allows you to measure the distance an object is from the device, as well as the speed and the acceleration of that object. If we decide that the origin (h = 0) is at the sonar device, we want to know what the height change is as we slide down the incline. For an angle below the horizontal of 9.74°, we see that our object has slid a distance 0.54 m, as measured along the incline itself. - Calculate the height change and report your answer as a negative number. (This value would be useful for calculating the change in gravitational potential energy, as we will do in the lab.) h=o earrow_forwardA baseball is dropped from an altitude h = 210 ft and is found to be traveling at 100 ft/sec when it strikes the ground. In addition to gravitational acceleration, which may be assumed constant, air resistance causes a deceleration component of magnitude kv², where v is the speed and k is a constant. Determine the value of the coefficient k. Plot the speed of the baseball as a function of altitude y. If the baseball were dropped from a high altitude, but one at which g may still be assumed constant, what would be the terminal velocity v? (The terminal velocity is that speed at which the acceleration of gravity and that due to air resistance are equal and opposite, so that the baseball drops at a constant speed.) If the baseball were dropped from h = 210 ft, at what speed vwould it strike the ground if air resistance were neglected? Answers: The drag coefficient, k= i The terminal velocity, v₂= Without drag, i i ft-1 ft/sec ft/secarrow_forwardYou're designing a highway so that the maximum centripetal acceleration on a curve is no more than 1.1 m/s2 . What is the minimum curvature radius to accommodate a 100 km/h maximum speed? Express your answer to two significant figures and include the appropriate units.arrow_forward

Oh vs. t h² vs. t h² vs. t/2 √h vs. t h² vs. t² Oh vs. √tarrow_forwardA space shuttle lands on a distant planet where the gravitational acceleration is 2.0 ( We do not know thelocal units of length and time , but they are consistent throughout the problem). The shuttle coasts along aleve, frictionless plane with a speed of 6.0. It then coasts up a frictionless ramp of height 5.0 and angle 0f 30°.After a brief ballistic flight, it lands a distance S from the ramp. Solve for S in local units of length. Assume theshuttle is small compared to the local length unit and that all atmospheric effects are negligible. Use x and y components.arrow_forwardThe acceleration due to gravity on the surface of a planet depends on the mass and size of the planet; therefore, other planets will have accelerations due to gravity other than 9.8 m / s2. Imagine an astronaut standing on an alien planet, which has no atmosphere, and throws a stone with a velocity of 7.35 m / s in a horizontal direction, dropping it at a height of 1.40 m above the surface of the planet. The rock hits the surface at a horizontal distance of 9.50 m from the astronaut. Find the magnitude of the acceleration due to gravity, in m / s2, on this alien planet.arrow_forward
