14-59. The rocket sled has a mass of 4 Mg and travels from rest along the horizontal track for which the coefficient of kinetic friction is μk 0.20. If the engine provides a 150 kN, determine the power output of constant thrust T = = the engine as a function of time. Neglect the loss of fuel mass and air resistance. T Prob. 14-59

Required information NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part Several forces are acting on a bolt as shown in the diagram below. It is desired to determine the resultant of all of the forces acting on the bolt. The axis of the bolt is at a 45° angle with respect to the x-axis. The line of action of force Pis parallel to the x-axis. The magnitudes of the forces and the angles labeled are as follows: P= 35 N S= 60 N T=31 N a=15° B= 65° Q = 53 N 8= 25° T S Using the x-and y-components of the resultant of the forces acting on the bolt, determine the magnitude of the resultant force. The magnitude of the resultant force is N.

The 10-lb block has a speed of 4 ft/s when the force of F= (8t^2) lbf is applied.Determine the velocity of the block when t= 2 s. The coefficient of kinetic friction at the surfaceis uk = 0.2

The crate, which has a mass of 245 kg is subjected to the action of the two forces. If it is originally at rest determine the distance it slides in order to attain a speed of 12 m/s. The coefficient of kinetic friction between the crate and the surface is 0.18 800 N 30° 4 1000 N
