At time t = 1s the instantaneous velocity is: At time t = 8s the instantaneous velocity is: b. Determine the instantaneous speed at each of these times. At time t = 1s the instantaneous speed is: At time t = 8s the instantaneous speed is: c. What is the average velocity between t = 1s and t = 8 s? Answer:

A round with a mass of m= 11.5 g is shot out of a rifle that has length L= 1.14 m. The round spends t= 0.14 s in the barrel. a. Write an expression, in terms of the given quantities, for the magnitude of the rounds acceleration, a, as it travels through the rifles barrel. You may assume that acceleration is constant throughout the motion. b. Calculate the numerical value for the magnitude of the rounds acceleration, a in m/s square. c. What is the numerical value of the net force F NET in Newton’s acting in the round?

A Ford Mustang can accelerate from 0 to 60 mph in a time of 6.0 s. A Mini Cooper isn't capable of such a rapid start, but it can turn in a very small circle 40 ft in diameter. Part A How fast would you need to drive the Mini Cooper in this tight circle to match the magnitude of the Mustang's acceleration? Express your answer in miles per hour. V= 5 ΑΣΦ mph

A small ball is attached to the lower end of a 0.800-m-long string, and the other end of the string is tied to a horizontal rod. The string makes a constant angle of 41.8° with the vertical as the ball moves at a constant speed in a horizontal circle. Part A If it takes the ball 1.55 s to complete one revolution, what is the magnitude the radial acceleration of the ball? Express your answer with the appropriate units. arad = Value Units ?
