- 5. A basketball is thrown from the roof of the school building as part of a science experiment examining gravity. The basketball is thrown from 25 feet above the ground at an initial velocity of 40 feet per second and at an angle of elevation of 30°. Write a set of parametric equations that model the basketball's horizontal and vertical position. 6. The basketball reaches its maximum height at t 0.625 seconds. Using your parametric equations from part 5, determine the location of the basketball at its maximum height relative to the starting point. %3DFor a lab report, I have to answer these questions and am confused on how to get these answers from the graphs. The lab is on projectile motion and velocity. I basically threw a ball upwards and recorded its flight on tracker. The two pictures I attached show the vertical velocity by versus time and the horizontal velocity vx versus time. From the velocity vs. time graph(s) determine the acceleration of the ball independently for each component of the motion as a function of time. What is the acceleration of the ball just after it is thrown, and just before it is caught or lands? What is the magnitude of the ball’s acceleration at its highest point? Is this value reasonable? Determine the launch velocity of the ball from the velocity vs. time graphs in the x and y directions. Is this value reasonable? Determine the velocity of the ball at its highest point. Is this value reasonable?On the map, let the +x-axis point east and the +y-axis north. An airplane flies at 880 km/h northwestward direction (i.e., midway between north and west). Find the components of its velocity. Enter the x and y components of the velocity separated by a comma. I understand the quadrant, and origin but not how to then figure components of airplane's velocity. Can you simply get me up to the speed?

- A toy racecar races along a circular race track that has a radius of 32 meters. The racecar starts at the 3-o'clock position of the track and travels in the CCW direction. Suppose the racecar has traveled 51 meters along the race track. How many radians has the racecar swept out? __radians What is the racecar's distance to the right of the center of the race track (in meters)? ____ metersShow that the radial acceleration is zero when 60 = radHi, below is the explanation to the problem cited. But I don't understand the answer to the last question #3: Determine its average acceleration during the 34.0 sec interval. I am lost; can you help? Thanks! A car initially traveling eastward turns north by traveling in a circular path at uniform speed as in the figure below. The length of the arc ABCis 214 m, and the car completes the turn in 34.0 s. An x y coordinate system is shown. Three points A, B, and C are shown on the graph. These points are joined by a dotted curve. Point A is on the negative y-axis, point C is on the positive x-axis, while point B is in the fourth quadrant IV at an angle of −35° with the x-axis. From point A the curve initially moves rightward along a circular path, curves upward to cross B and then meets C. An arrow indicating the velocity at point A points horizontally and to the right. An arrow indicating the velocity at point C points vertically upward. 1. What is the acceleration when the car is at…
