- A particle's velocity can have both magnitude (speed) and direction which vary as a function of time. A particle's velocity can have both magnitude (speed) and direction which vary as a function of time. True FalseYou drive 109 km/h east for 31 min, then 82 km/h north for 42 min Let the +x-axis point east and the +y-axis north. A) Find your average velocity for the entire trip. B) Find your average speed for the entire trip.A test rocket is launched by accelerating it along a 200.0m incline at 1.85m/s2 starting from rest at point A. The incline rises at 35.0o above the horizontal, and at the instant the rocket leaves it, it's engines turn off, and it is subject only to gravity (air resistance can be ignored) a) find the maximum height above the ground that the rocket reaches in m b) find the greatest horizontal range of the rocketbeyond point A
- Using the triangle method, determine the displacement of traveling: 100 km @ 30° SoW and then 40 km @ 70° EoS. A) 114 km @ 15.6° SoW B) 80.4 km @ 37.6° WoS C) 80.4 km @ 22.4° WoS D) 80.4 km @ 72.4° SoWneed help on incorrect answers.On the Apollo 14 mission to the moon, astronaut Alan Shepard hit a golf ball with a golf club improvised from a tool. The free- fall acceleration on the moon is 1/6 of its value on earth. Suppose he hit the ball with a speed of 29 m/sm/s at an angle 36 ⁰⁰ above the horizontal. A) How long was the ball in flight? B) How far did it travel? C) Ignoring air resistance, how much farther would it travel on the moon than on earth?
