Ship a is located 3.90 km north and 2.50 km east of ship b. ship a has a velocity of 21.0 km/h toward the south and ship b has a velocity of 40.0 km/h in a direction 37.0° north of east. what are the (a) x-component and (b) y-component of the velocity of a relative to b? (axis directions are determined by the unit vectors i and j, where i is toward the east.) (c) at what time is the separation between the ships least? (d) what is that least separation?

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?
