Two astronauts floating at rest with respect to their ship in space decide to play catch with a3-kg asteroid. Joe (whose mass is90 kg) throws the asteroid at12 m/s towardJesse (whose mass is62 kg). She catches it and throws it back at10 m/s (with respect to the ship).
What is Joe's speed right after his first throw?
m/s
What is Jesse's speed right after her first catch?
What is Jesse's speed right after her first throw?
What is Joe's speed right after his first catch
A skateboarder shoots off a ramp with a velocity of 6.4 m/s, directed at an angle of 55° above horizontal.
You have a 1.99-m-long stretched string with a mass of 19.5 g. When you oscillate the string at 440 Hz, Calculate the tension in the string
In the vertical case the maximum tension in the string is 18.0% larger than the tension that exists when the circle is horizontal. Identify the speed of the stone.
who is initially at rest, hops on her back and together they continue down the hill. Illustrate what is their speed at the bottom of the hill if the total vertical drop is 17.0 m? Gayle's mass is 50.0 kg, the sled has a mass of 5.00 kg and her bro..
find out where the coyote lands in the canyon.
A car is traveling at 50.0 mi/h on a horizontal highway, What is the stopping distance when the surface is dry and µs = 0.601
An incompressible fluid flows steadily through a pipe that has a change in diameter. The fluid speed at a location where the pipe diameter is 8 cm is 1.28 m/s. What is the fluid speed at a location where the diameter has narrowed to 4.00 cm.
What is the tension in the string.At one time, television sets used "rabbit-ears" antennas. Such an antenna consists of a pair of metal rods.
assuming the weight is evenly distributed.On a hot day in Las Vegas, an oil trucker loaded 37000 L of fuel. He encountered cold weather on the way to Utah, where the temperature was 23K lower than Las Vegas.
A rotating cylinder about 12.00 km in length and 8.00 km in diameter is designed to be used as a space colony. With what angular speed must it rotate so that the residents on it would experience the same acceleration because of gravity on Earth.
The system is released from rest, and the string moves without slipping over pulley. If the larger mass is traveling at a velocity of 2.25 m/s when it has dropped 1m, how much mechanical energy was lost due to friction in the pulley's axle.
