MY NOTES The center fielder for the school's baseball team throws a 0.150-kg baseball towards home plate at a speed of 30.0 m/s and an initial angle of 40.00. What is the kinetic energy of the baseball at the highest point of its trajectory? X Can you write an expression for the kinetic energy of the ball at any time? How does this expression for the kinetic energy of the ball at any time get modified in order to obtain an expression for the kinetic energy of the ball at the top of its trajectory? How is the speed of the ball at the top of its trajectory related to the initial speed of the ball? ] Supporting Materials Physical ConstantsA man does 4,460 J of work in the process of pushing his 2.90 x 10" kg truck from rest to a speed of v, over a distance of 26.0 m. Neglecting friction between truck and road, determine the following. (a) the speed v (in m/s) m/s (b) the horizontal force exerted on the truck (in N) 174984 X Can you write an expression which relates the work done on an object to the force acting on it, and the distance over which this force acts? N Physical ConstantsMY NOTES A cross-country skier slides horizontally along the snow and comes to rest after sliding a distance of 27 m. If the coefficient of kinetic friction between her skis and the snow is / = 0.080, determine her speed at the start of the slide. m/s Supporting Materials Physical Constants
