A possible spacecraft design uses a solar sail made of aluminized plastic. As sunlight reflects off the sail, radiation pressure drives the spacecraft outward away from the sun. If the sail material has a density of 600.0 kg/m3 and If the sail's area is 1.9106 m2. its thickness is 1 ?m, and the craft carries a 82.0 kg payload, what is its acceleration at the radius of the Earth's orbit?
A 1200-kg station wagon is moving along a straight highway at 12.0 m/s. Another car, with mass 1800 kg, Find the total momentum of the system
What should be the spring constant of a spring designed to bring a 1500 car to rest from a speed of 80 so that the occupants undergo a maximum acceleration of 5.
Engineers can determine properties of a structure that is modeled as damped spring oscillator-such as a bridge-by applying a driving force to it, What is the oscillator\'s damping constant? (kg/s)
Children are playing on a vertical slide that is 10m high. If humps were added to this slide, but the height remained constant, how would this effect the final speed
