Problem 9: An archer}.r bow is drawn a distance d: 0.45 m and loaded with an arrow of mass m = 0.062 kg. The how acts as a spring with a spring constant of I: = 121 Non, and the arrow flies with negligible air resistance. To simplify your work, let the gravitational potential energy be zero at the initial height of the arrow. a'theesperttaeom tracking id: 93:69 4E (73 4-5 MAD 30566:.

Part (a) How fast, in meters per second, will the arrow be traveling as it leaves the how? Numeric : A numeric value is expected and not an expression. 1'0 = Perl (b) If the arrow is shot at an angle of 6' = 45" above the horizontal, how high, in meters above the initial height, will the arrow be when it reaches its peak? Numeric : A numeric value is expected and not an expression. h = Problem 10: A jogger with mass m = 75 kg uses energy at a rate of P = 755 W when she jogs on horizontal ground at a constant speed of s = 2.1 m/s. The efficiency of her "human engine" however, is e = 0.39. (In other words, the power used for locomotion is e = 0.39 times the total power.) @theexpertta.com - tracking id: 9N69-4E-C3-45-84AD-30566.

Part (a) Write an expression for the rate of energy expenditure when she jogs at the same constant speed up a slope of o = 5.3 degrees. Assume whatever frictional or drag forces are the same in each case. Your answer should be in terms of the symbols given in the problem statement and g (9.80 m/s2). Expression : P= Select from the variables below to write your expression. Note that all variables may not be required. cos(a), cos(Q), cos(0), sin(a), sin(Q), sin(0), y, 0, d, e, g, m, n, P, s Part (b) What is the rate of energy expenditure when she jogs up the slope, in watts? Numeric : A numeric value is expected and not an expression. P =
