- Imagine a small moon with a mass equal to 1.3 times the mass of the Earth's moon. How much work is done y this moon on a 1,331 kg meteor which comes from outer space and impacts the surface of the moon? You should assume that the radius of this moon is equal to the radius of Earth's moon. Where the radius of Earth's moon = 1,738 km.As shown in the figure below, two masses m, = 4.30 kg and m, which has a mass 60.0% that of m., are attached to a cord of negligible mass which passes over a frictionless pulley also of negligible mass. If m, and m, start from rest, after they have each traveled a distance h = 1.70 m, use energy content to determine the following. (a) speed v of the masses m/s (b) magnitude of the tension Tin the cord NTwo astronauts with masses m1 and m2 are moving with the velocity utogether. They push each other off in the direction perpendicular to u,spending the energy E. What is the angle between the velocities of theastronauts after the push-off?
- answer vii) onwards and dont use chatgpt thank you!At NASA's Zero Gravity Research Facility in Cleveland, Ohio, experimental payloads fall freely from rest in an evacuated vertical shaft through a distance of 132 m. (a) If a particular payload has a mass of 28 kg, what is its potential energy relative to the bottom of the shaft? (b) How fast will the payload be traveling when it reaches the bottom of the shaft? Convert your answer to mph for a comparison to highway speeds.
