A box of mass m is resting in the flat bed of a truck which is stopped at a red light on a road which slopes upward at an angle qabove the horizontal. The coefficients of friction between the box and the truck bed are given by μs and μk.The light turns green and the truck begins to accelerate.Write all answers in terms of variables given in the problem and any appropriate constants. 1)Draw a free body diagram for the box. 2)Find the maximum acceleration amax of the truck such that the box remains in the exact same place in the truck without sliding. 3)Assume the truck accelerates at a rate greater than the maximum found in part b. (atruck> amax). From the perspective of someone sitting in theback of the truck with the box, the box will beginaccelerating toward the back of the truck. Express this acceleration abox in terms of m, the distance to the back of the truck L, and the kinetic energy K of the box just before it hits the back of the truck.
Lost in Space Context A space shuttle drifts through space. At one point, its motors are turned on for a certain amount of time, which exerts a force perpendicular to its initial trajectory. Your objective is to determine the speed vector of the shuttle when the engines turn off. Constraints The mass of the ship is known, as well as its initial speed.The length of time the motors are on is known.The force generated by the motor is known and assumed to be constant. Modelization Models the modulus of the final speed (in km/h) according to the known parameters. Then model the angle the shuttle will travel after the motors turn off. This angle is the smallest angle measured with respect to the initial direction. Then test your model with the following parameters: Initial velocity: 460 km/h; Shuttle mass: 2098000 kg; Engine ignition duration: 13 s; Net force of motors: 4700000 N.
