Question four:
Find the magnitude and direction of the resultant of each pair of vectors given:
vx = 5 m/s, vy = -7 m/s, vR =
ax = -2 m/s^2, ay = -4 m/s^2, aR =
Δx = 3 m, Δy = 6 m, R =
Question five:
Four forces act on an object as follows:
Fx1 = 150 N
Fx2 = -200 N
Fy1 = -75 N
Fy2 = 125 N
Find the resultant force acting on the object (magnitude and direction).
Question Six:
Ex: A boat travels north, up a stream, with a velocity of 5 m/s. The current in the stream is 2 m/s east. What is the resultant (net) velocity?
