Question

Plane A in Figure Q1 is flying along a straight-line path at
velocity of 140 m/s, whereas plane B is flying at 110 m/s
along a circular path having a radius of 1 km and
slowing down at a rate of 40 m/s². If plane A is accelerating
at 15 m/s², determine at that instant shown:
a) velocity of plane B relative to plane A
acceleration of plane B relative to plane A
b)
B

A motorcycle begins at rest at t0 = 0 seconds. The motorcycle starts moving, and eventually covers a distance d = 840 m, in a time tf = 189 s. In a coordinate system with north being the positive x-direction, the motorcycle's motion is in the northern direction (see figure). 1. What was the motorcycle's average velocity in in the northern direction vavg,N, in this period in meters per second? 2. If the motorcycle's final velocity at tf was 12 m/s, what was the motorcycle's average acceleration in the northern direction, aavg,N, during this period in m/s2?
