Question
A 137 kg boat is trying to go, from the
origin (as shown in the figure), straight
across the river at a speed 0.7198 m/s in
the y-direction. The current in the river,
however, flows to the right and apply a net
force of 100 N (x-direction).
a) What is the position vector of the boat
after 2 seconds.
b) What is the velocity of the boat after 3
seconds.
Vboat,y
Initial position of the boat is:
Ij = <
Fnet.x
After time of 3 seconds the position of the
boat is:
r3 = <
J>
