1. A boat heads east accross a stream with a velocity of 20.0 m/s. The stream flows from the north at 5.00 m/s.
A) What is the resultant velocity of the boat as seen by an observer on the starting bank of the river?
B) If the stream is 100m wide , how much time does it take the boat to reach the other side?
c) How far downstream is the boat when it reaches the other side
2. A plane heads east at 200 m/s. The wind blows nort at 50.0 m/s. What is the planes resulutant velocity as seen by an observer on the ground?
3. A ball is inittially rolling 3.5 m/s (s). Due to uneven ground, it ends up travelling 4.2 m/s (E) after 2.1s. Calculate the acceleration of the ball.
