Running on a treadmill is slightly easier than running outside because there is no drag force to work against. Suppose a 60 kgkg runner completes a 5.0 kmkm race in 17 minutes. A) Determine the drag force on the runner during the race. Suppose that the cross section area of the runner is 0.72 m2m2. Express your answer with the appropriate units.     B) What is this force as a fraction of the runner's weight? Express your answer numerically.

Problem 1 Not So Simultaneous = The positions of two masses, ma and mb, are described by the equations: a(t) 3A sin (4wt) and xb (t) = 2A sin (3wt). (a) Not including t = 0, what are the first three times that the masses will pass through their respective equilibrium positions simultaneously? (b) Find the two expressions that would describe each mass' velocity. What were the velocities at the times you found in part a?

#1) Use Newton's Second Law Analysis to solve the following problem. , 1 - sketch and FBDs, 2 - write 0 down force equations in all dimensions, and 3 solve for requested variable. Two boxes, connected by a rope, are at equilibrium (need to consider friction on the incline). Box B is not touching the incline, it is just hanging from the outer rim of the pulley. Assume the magnitude of the tension force is greater than the magnitude of the wx component of mass A for part A (this should help you determine the direction of the static friction force). Draw the FBD for both box A and box B separately. Use N, for Normal Force, use fs for the static friction force, use proper variations of wx and wy for the weight components (two masses here, so they should have different labels not just wx and wy for both, you need to be able to tell them apart), and use T for the Tension Force. Somewhere in your work show what your variations of the magnitudes of wx and wy are in terms of the masses and g…

A 125 kg box is pushed up a ramp with a force of 100N applied at a 30 deg below the horizontal.  Coefficient of static friction is 0.9. 1. What is the normal force on the box? 2. What is the friction force on the box? 3. What is the largest friction force could be?

1.) Consider the diagram below. Mass Ma = 5kg and Mb = 50kg. The coefficient of kinetic friction between the black Ma and the table top is .2 = uk. Assume the tension in the cord is uniform throughout its length, the acceleration of each block is the same, and the pulley has no mass or friction. Calculate: a.) The acceleration in the system. b.) The tension T in the cord. mA mB

Pls answer asap. Thank you Note: Computation must be complete and answer in 2 decimal places.

d. Force is a vector quantity and thus has both a magnitude and a direction. A vector can be represented graphically by a line drawn to scale in the direction of the line of action of the force. To distinguish between vector and scalar quantities, various ways are used. Identify and explain threeof these ways.

1. A 20,000 pound truck is parked on a 15° slope. Find the force required to keep the truck from rolling down the hill (that is, find the magnitude of the vector component of the weight of the truck that is parallel to the slope). 2.Determine the vector v with magnitude of 30 that makes an angle of 120° with the positive xaxis. State the vector in either ordered set or unit vector notation with components written as exact values (simplified radical form).
