1.Find the absolute value of the magnitude of force vector B if the resultant force= 1000 lb, force vector A= 1000 lb, and the resultant forms a 45 degree angle with B, and vector B runs parallel to the y axis. Also find the angle in degrees between vector A and the resultant.
2.A particle is moving with a velocity of Vo when s=0 and t=0. If it is subjected to a deceleration of a = (-K)v^3, where K is a constant, determine its velocity and position as functions of time.
3.The acceleration of a particle traveling along a straight line is a=(1/4)s^1/2 m/s^2, where s is in meters. If v=0, s=1 m when t=0, determine the particle's velocity at s=2m
