It takes 35 seconds for the 50-Mg tugboat to increase its speed uniformly to 25km/h, starting from rest. The barge has a mass of 75 Mg. The propeller provides the propulsionforce F which gives the tugboat forward motion, whereas the barge moves freely. Determine Facting on the tugboat.

2. Determine the kinetic energy of the 60-lb block A at this instant if the 40-ib block B is traveling uphill with a speed of 1.5 ft/s. Also calculate the kinetic energy of block B. 60° 30

Block A is 30kg And Block B is 20 kg

The 214000-lb space-shuttle orbiter touches down at about 222 mi/hr. At 182 mi/hr its drag parachute deploys. At 40 mi/hr, the chute is jettisoned from the orbiter. If the deceleration in feet per second squared during the time that the chute is deployed is -0.000200v2 (speed v in feet per second), determine the corresponding distance s traveled by the orbiter. Assume no braking from its wheel brakes. Answer: s = i ft
