I Gen Physics

  1. Jan 28, 2017 #1
    Thanks in advance for the help! Small explanation would also be great!

    1. You toss a ball upward and it rises to its highest point in 1 second. With what initial velocity did you toss it?

    Suppose Sandra Bullock is in a space capsule that is initially at rest (v0 = 0) with respect to a space station 4 km away. She only has a minute of air left and so needs to get there fast. However, the rockets on the capsule are almost out of fuel. They can only burn for a total of 6 seconds.

    With the help of George Clooney’s ghost, she determines to accelerate at a rate of 30 m/s2 for 3 seconds, coast for a while, then decelerate at a rate of 30 m/s2 for 3 seconds until she arrives at the space station with zero velocity (vf = 0).

    Does she make it in time?

    3. Part c for this question. The image is attached.
