A river flows with a constant speed of 2.1 km·hr−1. A motorboat makes a round trip between two boat landings on the the same bank and in a straight section of the river. The distance between the two landings is 3.6 km, and it takes 1 hour 40 minutes for the boat to make the round trip if the boat moves at a constant speed with respect to the water. Figure 2 shows a diagram of the boat on the river.

- Problem 1: A car is moving on a straight road in a fixed direction at a constant speed of v = 31 km/h with respect to the road. You wish to state the kinematic vectors of the motion of the car by using a Cartesian coordinate system whose positive x-axis is pointed in the direction of the motion of the car and the origin is fixed at some point on the road. Part (a) What is the expression for the velocity of the car, using the speed v and the unit vectors i, j, and k?In a time of 2.67 h, a bird flies a distance of 86.7 km in a direction 30.2 degrees east of north. Take north to be the positive y direction and east to be the positive x direction. Express your answers in km/h. What is the x component of the bird’s average velocity? What is the y component of the bird’s average velocity?Any assistance with this physics problem would be great!
- I am currently learning about kinematics in my physics class. For one of the questions, it asks me to solve a question that asks me to find the magnitude of acceleration. I have found answers ranging between 3 and 4, but everytime I put my answer into Webassign it is wrong. I was wondering how I would find the magnitude of acceleration given the time and distance. Thank youA cart is propelled over an its greatest y coordinate? xy plane with acceleration components a, = 6.8 m/s? and a, = -1.5 m/s2. Its initial velocity has components Vox = 7.3 m/s and voy = 12.4 m/s. In unit-vector notation, what is the velocity of the cart when it reaches Number UnitsCities A and B are connected by a straight road of total length 200 miles.Two cars depart cities A and B at the same time, moving towards each other. The A-car travels at 60 miles per hour, and the B-car at 40 mph. At the same time, a fly starts off from the front bumper of the A-car flying at 100 mph. It flies towards city B until it touches the bumper of the B-car, and then flies back, touches the A-car, flies back, etc, until the cars collide and the fly is squashed. The standard trick question is - what is the total distance traveled by the fly? At first sight one would think that the problem should be solved by the series summation, but that’s not necessary - the cars meet after 2 hours, and during that time the fly traveling at 100 mph covers exactly 200 miles. Now that you know the answer, solve this problem using the series summation [1].

The figure below shows a portion of the path traveled by the helicopter, as viewed looking down from above. The helicopter's path includes three straight portions between points "1" and "2", points "4" and "5", and points "7" and "8", each of which has a length of 4000 m, as shown in the figure. It takes the helicopter 2000 seconds to travel along each of these straight portions of its path.

- In a naval battle, a battleship is attempting to fire on a frigate. The battleship is a distance d₁ = 2,200 m to the east of the peak of a mountain on an island, as shown in the figure below. The frigate is attempting to evade cannon shells fired from the battleship by hiding on the west side of the island. The initial speed of the shells that the battleship fires is v, = 245 m/s. The peak of the mountain is h = 1,640 m above sea level, and the western shore of the island is a horizontal distance d₂ = 290 m from the peak. What are the distances (in m), as measured from the western shore of the island, at which the frigate will be safe from fire from the battleship? (Note the figure is not to scale. You may assume that the height and width of the frigate are small compared to d, and h.) less than m, or more than d₁ m 4A boxer's fist and glove have a mass of m = 1.04 kg.
