Assume that you are driving down a hill in Jabaal Akhdar in a winter season. The inclination of the hill e is 7.8degrees. The roads are covered partially with ice (coefficient of kinetic friction µ, = 0.2). When you apply thebrake, the car sliding down to stop from an initial speed of 15 m/s. What is the stopping distance of the car (inm)? Hint: final velocity of car = 0.Note: write the answer with one decimal place.

Given: angle of inclination: 7.8o μk=0.2 component of gravity acting on the car down the hill= g…

Suppose you throw an object from a great height, so that it reaches very nearly terminal velocity by time it hits the ground. By measuring the impact, you determine that this terminal velocity is -49 mi sec.A. Write the equation representing the velocity v(t) of the object at time t seconds given the initial velocity v0 and the fact that acceleration due to gravity 9.8 m/sec2. (Here, assume you're modeling the falling body with the differential equation dy/dt = g-kv, and use the resulting formula or v(t) found in the Tutorial. Of course, you can derive it if you'd like.)B. Determine the value of k, the "continuous percentage growth rate" from the velocity equation, by utilizing the information given concerning the terminal velocity.C. Using the value of k you derived above, at what velocity must the object be thrown upward if you want it to reach its peak height after 3 sec? Approximate your solution to three decimal places, and justify your answer.
