A log is floating on swiftly moving water. A stone is dropped from rest from a 73.6-m-high bridge and lands on the log as it passes under the bridge. If the log moves with a constant speed of 5.63 m/s, what is the horizontal distance between the log and the bridge when the stone is released? Number Units​

An astronaut in space cannot use a scale or balance to weigh objects because there is no gravity. but she does have devices to measure distance and time accurately. she knows her own mass is 77.4 kg , but she is unsure of the mass of a large gas canister in the airless rocket. when this canister is approaching her at 3.50 m/s , she pushes against it, which slows it down to 1.30 m/s (but does not reverse it) and gives her a speed of 2.60 m/s . what is the mass of the canister?
