Quantities that have magnitude and direction but not position. Some examples of vectors are velocity, displacement, acceleration, and force. They are sometimes called Euclidean or spatial vectors.
Let the velocity vector be v(t) = (6 cos(3t), 8 exp(2t), 3t2). Compute the acceleration vector a(t).
A particle moves in the xy− plane according to the law x=at, y=bt2, where a>0, b>0.
Determine the particle’s trajectory y(x) and sketch its graph.
Determine the speed of the particle as a function of time.
Find the angle ϕ between the velocity vector and the x−axis.
A sheet of water of uniform thickness (h = 0.03 m) flows from the device shown in the figure below. The water enters vertically through
the inlet pipe and exits horizontally with a speed that varies linearly from 0 to 11 m/s along the 0.2-m length of the slit. Determine the y
component of anchoring force necessary to hold this device stationary.
