The nurse is caring for a patient that has been prescribed nitroglycerin for chest pain. During the medication reconciliation, the nurse discovers the patient has recently taken sildenafil. The nurse knows that the concurrent use of these two medications could lead to severe hypotension. This is an example of which type of drug interaction?

A rod assembly rotates around its z-axis. The mass C is 10 kg and its initial velocity is 2 m/s. A moment (M = 8t2 + 5 N·m ) and force (F=60 N) both act as shown. What is the angular impulse about z-axis due to only external force F, after 2 seconds?

A man hits the 50-g golf ball such that it leaves the tee at an angle of 40° with the horizontal and strikes the ground at the same elevation a distance of 20 m away. Determine the impulse of the club C on the ball. Neglect the Impulse caused by the ball’s weight while the club is striking the ball.

A sports car has a mass of 2 Mg and an engine efficiency of e = 0.65. Moving forward, the wind creates a drag resistance on the car of FD = 1.2v2 N, where v is the velocity in m/s. The car accelerates at 5 m/s2, starting from rest. What is the magnitude of the velocity of the car when t=4 s.

Two equal-length springs having a stiffness kA = 300 N/m and kB = 200 N/m are “nested” together in order to form a shock absorber. If a 2-kg block is dropped from an at-rest position 0.6 m above the top of the springs, determine their deformation when the block momentarily stops.
