I am working on finding the inital velocity of a class II projectile and am having trouble determining the right amount of sig figs. The taken measurements of the initial position of x goes to 4 sig figs, as well as the final position for y. With that being said, I am trying to find the initial velocity of x and y separately through trionometry. For example, if I have an equation for the initial velocity of x with an angle of 40, then Vox=Vocos40 My question is, since the measured value for my angle is two significant figures, is my answer Vox=.76Vo also in two sig figs because it goes by the two significant figures from my measured angle, or should I go to four significant figures to match my measured values for x and y?
An archer fish spies a meal of a grasshopper sitting on a long stalk of grass at the edge of the pond in which he is swimming. The fish is to successfully spit at and strike the grasshopper, which is 0.200 m away horizontally and 0.335 m above his mouth. What angle (in degrees) above the horizontal must he spit?
Athena is planning a flight from Toronto to Montreal, which lies due east of Toronto. Her aircraft flies at a speed of 800.0 km/h in still air. A wind of 50.0 km/h is blowing from [W 30.0° N]. In what direction must she aim the airplane to fly directly to Montreal ?
Brandon is on one side of a river that is 60 m60 m wide and wants to reach a point 300 m300 m downstream on the opposite side as quickly as possible by swimming diagonally across the river and then running the rest of the way. Find the minimum amount of time if Brandon can swim at 2 m/s2 m/s and run at 4 m/s.
A small, battery-powered, electric motorboat that can travel at a speed of 1.80 m/s in still water is operating in a river with a flow speed of 1.35 m/s. For each of the following two cases, determine the requested information for a river that is 220 m wide. (a) Case 1: when the boat is pointed straight across the river, determine the speed Vbl of the boat as viewed by someone on land, the distance d the boat is swept downstream before reaching the other side, and the time t it takes the boat to make the crossing. Vbl = m/s d = t1 = (b) Case 2: if the boat operator wants to land the boat straight across the river from the launch site, determine the speed Vbl of the boat as viewed by someone on land, the angle ß upstream at which the boat should be pointed, and the time t2 it takes the boat to make the crossing. Vbl = m/s ß = t2 = S
Omar swims across a river at a velocity of 2.50 m/s [30o N of E] with respect to the water. The current is 5.4 m/s [E]. She crosses the river in 425 seconds. Determine the width of the river.
A person sitting in a train that is moving at 10.65 m/s due east is watching a crow fly over. The crow is flying 7.38 m/s at 12.76 degrees south of East. What is the apparent velocity of the crow relative to the passenger, Vcp, in the train? (Take the +x direction to be east. Calculate angles from the +x axis.)

A plane flies directly West at a velocity of 250.km/hr if there is no wind. What will be the plane’s resultant velocity to an observer on the ground if the plane encounters a constant 40.0km/hr wind from the East ?
The captain of a small plane starts his journey by proceeding east. The speed of the plane with respect to still air is160 km/h. A sudden north wind starts to blow at a constant speed of 71.0 km/h. As seen by people on the ground, what is the angle made between the direction of motion of the plane with repectto the east?
A plane departs from Toronto and heads to Ottawa travelling at 529.9 km/h [N33.67°E, relative to the ground]. If the plane experiences a jet stream of 177.9 km/h [W, relative to the ground] during the trip, calculate the velocity of the plane with respect to the jet stream.
Dr. L. and his cat Kepler are coming home from fishing. They ended their trip on the southbank of a 1200 m wide river, directly across from where Caroline is waiting to pick them upon the north bank. They are in identical boats that travel at 4 m/s (VB) on still water. Theriver is normally ‘lazy’ and flows with negligible velocity. On a calm day, if they pointed theboats north, they would cross the river in exactly 300s. However, today, the river is flowingdue east with a constant velocity (VW) of 1 m/s relative to the ground. Kepler, because shedoesn’t know better (she is a cat after all), has not taken this into account. Without payingattention, Kepler keeps the boat pointed due north for the entire trip. A) Relative to the ground, what is Kepler’s velocity? Derive an algebraic solution(in terms of VB and VW only) and then give a numerical answer (three significant figures isfine) expressed in degrees relative to due north (e.g. ‘42.3° west of north’).
