Dynamics 2 - velocity, acceleration

Experimental data indicates that in a region downstream of a given louvered supply vent the velocity of the emitted air is defined by v= 0.18Vo/x, where v and x are expressed in m/s and meters, respectively, and Vo is the initial discharge velocity of the air. for Vo = 3.6 m/s, determine: a) the acceleration of the air at x = 2m b) the time required for the air to flow from x= 1 m to x = 3m.

Moment of force problem

1. Three forces F1, F2, and F3 or magnitude 40 N, 100N and 20 N are acting on a point. The direction of the forces are 0,-30 and +120 degrees from the positive X axis. Determine the magnitude and direction of the resultant force.

Newton's 2nd Law - Kinetics of a particle

Dynamics 12.8 A car has been traveling up along a 2 percent grade at a constant speed of 55 miles/hr. If the driver does not change the setting of the throttle or shift gears as the car reaches the top of the hill, what will be the acceleration of the car as it starts moving down the 3 percent grade? Dynamics 13.7 A 24-lb package is placed with no initial velocity at the top of a chute. Knowing that the coefficient of kinetic friction between the package and the chute is 0.25, determine a) How far the package will slide on the horizontal portion of the chute b) The maximum velocity reached by the package c) The amount of energy dissipated due to friction between A and B ... click for more
