Suddenly the retrorockets are fired and ... The spacecraft is traveling with a velocity of +3250m/s. Suddenly the retrorockets are fired and the spacecraft begins to slow down with an acceleration whose magnitude is 10m/s^2. What is the velocity of the spacecraft when the displacement of the craft is 215km, relative to the point where the retrorockets began firing?

#1 An engineer wants to build a track to test the acceleration of a new vehicle to 100mph and back to a complete stop. The vehicle accelerates from rest to 100mph in 5.2s, and when the brakes are engaged, its maximum deceleration is 16m/s2. (a) What is the minimum required length of the track? (b) Plot the velocity vs time of one run where the vehicle accelerates to 100mph and then immediately decelerates to a complete stop. #2. Freight trains...

Question 19 and 20
The package follows a cured path, but it is always vertically below the airplane. The package follows a straight line path that lags behind the airplane. A car travels due east at 12 m/s. It makes a turn due north and continues to travel at 16 m/s. What is the net velocity of the car? 20 m/s, 53 degree with the east 25 m/s, 37 degree with the east 28 m/s, 35 degree with the east...

A spacecraft is traveling with a velocity of v0x = 4740 m/s along the +x direction. Two engines are turned on for a time of 929 s. One engine gives the spacecraft an acceleration in the +x direction of ax = 2.11 m/s2, while the other gives it an acceleration in the +y direction of ay = 8.76 m/s2. At the end of the firing, what is a) vx and b) vy?
