Hint: This is a multiple step problem in which you must derive the variables needed (mass and distance under constant acceleration ) in step one and then apply those values to the final solution of the problem in step two, that is calculate the work done. 93.50 748N 591.5 442,442J or 442.442kJ or 4.42x10^5 Question 7 5 out of 5 points When an aircraft returns to the aircraft carrier and lands, it goes from 246 mph to 0 mph in 2.7 seconds. What is the acceleration in this case? CAUTION: Think about what is happening in a physical sense and that it matches your answer. -40.73 m/s^2 Question 8 5 out of 5 points A pilot will black out if experiencing a centripetal acceleration of greater than 5g’s. An F-16 going 155 m/s enters a tight turn of radius 399 m. The pilot in this case is experiencing how many g's? 6.14g Question 9 5 out of 5 points A 194.7 kg satellite is in a circular orbit of 26,273 miles (42,300,000 m) in radius. The force keeping the satellite in orbit is 46.7 N. What is the velocity (speed) of the satellite? 3185 m/s Question 10 5 out of 5 points A 0.09 kg bullet traveling at 658 m/s hits a 6.2 kg block of wood and stays in the wood. What is the velocity (speed)of the wood block immediately after the bullet hits it? 9.41m/s Question 11 5 out of 5 points
It takes an elevator 2 minutes to raise a vehicle with a mass of 383 kg from the floor to a height of 6 meters. What size (power) motor (in watts) does it take to do the job? Hint: this is a multiple step problem in which you must derive the variables needed to solve for problem in step one and then apply those values to the final solution of the problem. Watch your units.
