SAP ASAP ASAP SHOW ALL WORK PLEASE A rocket takes off vertically from rest from the surface of Mars, where the acceleration due to gravity on Mars (gm) =3.71 m/s2. a) Assume that gm stays constant while the fuel is being used to propel the rocket. Write out a general expression for the velocity of the rocket in terms of ve, mo, m, t, and gm b) If the speed that the fuel leaves the rocket is ve = 1000 m/s, and the rocket loses 60% of its mass while burning fuel for 20.0 sec, what is the final speed of the rocket?

Help with this homework question would be great, thanks!

Hey im stuck on this question You are on the plane neptune and want to determine the acceleration due to gravity, g. You have a stopwatch and a toy gun that can launch a ping pong ball vertically upwards with an initial velocity of 7.5 m/s. Describe, in words, how you would perform an experiment to determine the acceleration due to gravity. Be sure to describe the variables you would measure, the equations you would use and the assumptions you would make. Make sure to include a diagram of the physical situation, label know and unknown quantities with units, coordinate system. Please use grade 12 kinematics and label the variables as v1, v2, a (Acceleration), t (time), d (displacement) Thanks!

What was the ball's initial speed in m/s? assume g = 9.8m/s?. Answer: 9:41 PM O Type here to search 日 amazon 10°C G ENG 2021-10-17 %2:

Page The heights of a rock after t seconds, when propelled straight up with an initial speed of 80 feet per second from an initial height of 20 feet, can be modeled by the function s(t) = -16t² + 80t +20. When will the height of the rock be 50 feet? Round your answer to the nearest tenth of a second. C

Pls help ASAP. Pls show all work, steps and calculations please.
