A car comes to a bridge during a storm and finds the bridge washed out. The driver must get to the other side, so he decides to try leaping it with his car. The side the car is on is 20.6 mm above the river, whereas the opposite side is a mere 1.9 mm above the river. The river itself is a raging

Estimate the thickness of the Earth's atmosphere. From your chemistry class, you know that the most common speed of a nitrogen molecule is 700 m/s. The molecules' velocity is pointed along random directions, but some molecules head straight up; i.e. directly away from the Earth's center. Consider the thickness of the atmosphere as the highest point that such a nitrogen molecule can fly to, if it goes straight up. What is the altitude? m

A drowsy cat is looking at a window from across the room, and sees a flowerpot that sail first up and then down past the window. The pot is in view for a total of 0.54 s, and the top-to-bottom height of the window is 1.86 m. How high above the window top does the flowerpot go?

r The speed of a boat in still water is V. A river flows with a speed of v₁. The boat travels distance of 14 miles downstream in a river in 1 hour. However, the return journey takes 2 hours. Calculate the V and V₁. Hint: Velocity = displacement/time. Displacement can be positive of neagtive depending on the direction. You will first need to set up the equations by taking into account the resultant velocity of the boat in flowing water. Consider the direction the river is flowing to be positive. Set up two equations, one for the downstream journey and one for the upstream journey, in terms of "V" and "v": Do V" and "v, add or substract downstream to give the resultant downstream velocity? Do v" and "v, add or substract upstream togive the resultant upstream velocity? Use the upstream direction as negative. The resultant upstream velocity should be negative. Equation 1 (downstream): Equation 2 (upstream): Solve for: V₁² vb Write an algebraic expression; do not use numerical values except…

3.2 A rhinoceros is at the origin of coordinates at time t1=0t1=0. For the time interval from t1t1t_1 to t2t2t_2 = 13.0 ss , the rhino's average velocity has x-component -3.8 m/sm/s and y-component 5.2 m/sm/s .1. At time t2=t2= 13.0 ss what is the x-coordinate of the rhino? 2. At time t2=t2= 13.0 ss what is the y-coordinate of the rhino? 3. How far is the rhino from the origin?
