Question

A plane is preparing to takeoff at one end of a
runway. The length of the runway is 2.6 km,
and the mass of the plane is 112 x 103 kg. The
takeoff speed of 247 km per hour has to be
achieved within the length of the runway.
Calculate the Force that the engines have to
exert to achieve this speed in the given
distance, if it starts from rest. Write your answer
in kilonewtons.

A 2 kg box is put on the surface of an inclined plane at 27 degrees with the horizontal. The kinetic coefficient of friction is μ = 0.3. If released from rest at a height of 3 meters, how long would it take the box to reach the bottom?
In the figure, the 200-lb crate is being pulled up the slope by the motor M. If the velocity of the point P is 2s³ ft/s (where s is the displacement of the crate), and the coefficient of kinetic friction between the crate and the slope is u = 0.2, what will the towing force applied by M be when the box has moved 10 ft up the slope?
