The block of mass M slides back along the horizontal surface with a coefficient of kinetic friction ?k and eventually comes to a rest. In terms of v4, how far does the block slide during this final leg of its journey, and how long does this take? Can you calculate the total trip time from bullet impact to now?
A battery with an emf of 12.00 V has an internal resistance r. When connected to a resistor R, the terminal voltage is 11.70 V, What is the energy dissipated in the battery's internal resistance in 4.20 minutes
What is the total charge of the thorium nucleus? (The neutral thorium atom has 90 electrons.), What is the magnitude of the force on an electron at that distance
A child slides down a slide with the 29 degree incline, and at the bottom her speed is precisely half of what it would have been if the slide had been frictionless. Compute the coefficient of sliding between the child and the slide.
Donovan Bailey set a world record for the 100-m dash on July 27, 1996. find the time that was recorded on Earth
A block of wood is held in place against a rough wall by someone pushing on it with a force directed upward at 28 degrees above the horizontal, What is the mass of the block of wood
Lunar astronauts placed a reflector on the moon's surface, off which a laser beam is periodically reflected, What percent accuracy is this, given the average distance to the moon is 3.84
A 9kg block is connected by a string over a light pulley to a 5kg block that is sliding over a flat table (i.e. the 9kg is pulling the 5kg off the table). If Co-efficient of kinetic friction is 0.200, find the tension in the string.
Two boats start together and race across a 62-km-wide lake and back. Boat A goes across at 62 km/h and returns at 62 km/h. Boat B goes across at 31 km/h, and its crew, realizing how far behind it is getting, returns at 93 km/h.
A cowboy at a dude ranch fills a horse trough that is 1.5 m long, 60 cm wide and 40 cm deep. He uses a 2.0cmdiameter hose from which water emerges at 1.5m/s. How long does it take him to fill the trough.
Consider a spacecraft in an elliptical orbit around the earth. At the low point, or perigee, of its orbit, it is 300km above the earth's surface; at the high point, or apogee, it is 2500km above the earth's surface. What if the rockets were fired ..
