The acceleration of high-speed aircraft is sometimes expressed in g’s (in multiples of the standard acceleration of gravity). Determine the net force, in N, that a 90-kg man would experience in an aircraft whose acceleration is 6 g’s.
A loaded truck weighs 16(10^3)lb and accelerates uniformly on a level road from 15 ft/s to 30 ft/s during 4 s.
If the frictional resistance to motion is 325 lb, determine the maximum power that must be delivered to the wheels
What is the mass of an object that falls freely under the influence of gravity from an elevation of 100 m above the earth's surface? The downward velocity is 100 m/s and strikes the earth at 109.4m/s. Take g = 9.81 m/s2.
Ans. m=40kg
