Transcribed Image Text:An airplane is flying at a speed of 250 m/s relative to the ground. Inside the plane, a
bottle rocket goes off (I don't know how) and travels diagonally 20 meters toward
the front of the plane and 10 meters across the plane in 0.3 seconds. What is the
speed of the bottle rocket relative to the ground?
a) 344 m/s.
b) 348 m/s
c) 355 m/s
d) 359 m/s
e) 362 m/s
For fun: The speed of sound in air is 343 m/s. Will the bottle rocket cause a sonic
boom?
4. You kick a ball at a speed of 20 m/s at an angle 30° above horizontal. On its way
down, you see the ball just barely pass over the top of a 2 m tall fence.
a) How far away from you is the fence?
b) Calculate the angle of the velocity as the ball passes over the fence.
