Part C Now, observe the graphs of the horizontal and vertical components of velocity versus time. Change
the graphs to show Vx vs. t and vy vs. t.
What do you observe about the velocity components of the snowboarder before and after time t = 0?

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?
