- An average-sized asteroid located 5.0107km from Earth with mass 2.01013kg is detected headed directly toward Earth with speed of 2.0km/s . What will its speed be just before it hits our atmosphere? (You may ignore the size of the asteroid.)arrow_forwardProfessional Application Calculate the increase in velocity of a 4000-kg space probe that expels 3500 kg of its mass at an exhaust velocity of 2.00103 m/s. You may assume the gravitational force is negligible at the probe's location.arrow_forwardA single-stage rocket of mass 308 metric tons (not including fuel) carries a payload of 3150 kg to low-Earth orbit. The exhaust speed of the rockets cryogenic propellant is 3.20 103 m/s. a. If the speed of the rocket as it enters orbit is 8.00 km/s, what is the mass of propellant used during the rockets burn? b. The rocket is redesigned to boost its exhaust speed by a factor of two. What is the mass of propellant used in the redesigned rocket to carry the same payload to low-Earth orbit? c. Because the exhaust speed of the redesigned rocket is increased by a factor of two, why is the fuel consumption of the redesigned rocket not exactly half that of the original rocket?arrow_forward
- Two identical particles, each of mass 1 000 kg, are coasting in free space along the same path, one in front of the other by 20.0 m. At the instant their separation distance has this value, each particle has precisely the same velocity of 800 m/s. What are their precise velocities when they are 2.00 m apart? Figure P13 74arrow_forwardJupiter's moon Io has active volcanoes (in fact, it is the most volcanically active body in the solar system) that eject material as high as 500 km (or even higher) above the surface. Io has a mass of 8.93×1022kg and a radius of 1821 km. For this calculation, ignore any variation in gravity over the 500 km range of the debris. How high would this material go on earth if it were ejected with the same speed as on Io?arrow_forwardCalculate the increase in velocity (in m/s) of a 4810 kg space probe that expels 3210 kg of its mass at an exhaust velocity of 4.00 ✕ 103 m/s. You may assume the gravitational force is negligible at the probe's location. The answer is 4400 m/s given by the homework website I tried using the conservation of momentum and the conservation of kinetic energy but did not get the right answer.arrow_forward
- One hazard of space travel is the debris left by previous missions. There are several thousand mass is large enough to detect by radar orbiting the earth, but there are far greater numbers of very small masses such as flakes of paint. Calculate the force exerted by 0.140Mg of paint that's tracks a space shuttle window at a relative speed of 5.00×10^3 m/s and sticks , given The collision last 6.00 x 10^-8s such a collision chip the window of the ill-fated challenger in June 1983, causing $50,000 of damage. n? I used the symbol ^ to show exponentarrow_forward(Please include diagram or drawing) Two clay meteors, each with a mass m, collide in outer space and stick together. This collision occurs at a distance D from the center of the Earth. Following the collision, the combined meteors move towards the Earth. Before the collision: Meteor 1 has a velocity v1. Meteor 2 has a velocity v2. The velocities V1 and v2 are at right angles to each other. a) Calculate the fraction of kinetic energy lost during the collision of the two meteors. b) Determine the velocity of the stuck-together meteors just before they crash into the Earth assuming you know the mass and radius of earth. Air resistance can be neglected.arrow_forwardSuppose you have a situation where a bowling ball of 5kg collides with a bowling pin of 2.2kg. If the pin moves forward with a speed of 3m/s. and the ball continues forward with a speed of 1.8m/s what was the initial speed of the ball? (Ignore the rotation of the ball.)arrow_forward
- Astronomers estimate that a 2.0-km-diameter asteroid collideswith the Earth once every million years. The collision couldpose a threat to life on Earth. (a) Assume a spherical asteroidhas a mass of 3200 kg for each cubic meter of volume andmoves toward the Earth at 15 km/s How much destructiveenergy could be released when it embeds itself in the Earth?(b) For comparison, a nuclear bomb could release about 4.0x1016 JHow many such bombs would have to explodesimultaneously to release the destructive energy of theasteroid collision with the Earth?arrow_forwardYesterday you saw in the news that the Giant Asian Murder Hornet has migrated to North America. You didn't think much about it until today when one of those suckers crashed at high speed into the screen door at the back of your house (splat!). The thing hit the door so hard that the door swung shut!We will assume that GAMH had a mass of m = 0.069 kg and was moving with an amazing velocity of v = 9.2 meters/second. The GAMH splatted a distance d = 0.65 meters from the hinge. The door itself can be treated as a rod of mass M = 0.955 kg with a length of L = 1.00 meters rotating about its end.Determine all the following:Write the FORMULA for the moment of inertia of the door without the hornet: I = kg m2Write the FORMULA for the moment of inertia of the door with the hornet: I = kg m2Determine the angular momentum of the hornet before it collides with the door Lhornet = kg m2/sDetermine the angular velocity of the hornet-stained door after the collision ?2 =…arrow_forwardYesterday you saw in the news that the Giant Asian Murder Hornet has migrated to North America.
