A frog can swim at
1(m)/(s)
. It is on one side of a stream, at Point
A
and wants to swim to Point B on the other side of the stream, and 10 metres downstream. The stream is 5 metres wide and the current is
0.5(m)/(s)
. a) Calculate the angle, with respect to the shore, the frog must aim to land at point B. (5 Marks) b) How many seconds will it take the frog to reach point
B
? (4 Mark this is calculus geometric and cartesian vectors
