1. Graph the equations of motion of two mobiles x 1 = 250-10t and x 2 = 15t and determine the time and the place of their meeting. (3 points)
2. The distance between two localities A and B is d = 50km. A mobile starts from A with speed v 1 = 20km / h, and al
the second mobile, with speed v 2 = 40km / h, starts from B, in the same direction as the first mobile, but at t 02 = 2h after
departure of the first mobile. The movements of the two mobiles are uniform rectilinear.
a) Write the laws of motion of the two mobiles, with respect to A.
b) Find the time and place of the meeting of the two mobiles, compared to A.

The x-coordinate of a particle in curvilinear motion is given by x = 3.1t3 - 4.9t where x is in feet and t is in seconds. the y-component of acceleration in feet per second squared is given by ay = 2.3t. if the particle has y-components y = 0 and vy = 5.0 ft/sec when t = 0, find the magnitudes of the velocity v and acceleration a when t = 1.8 sec. sketch the path for the first 1.8 seconds of motion, and show the velocity and acceleration vectors for t = 1.8 sec. answers: v = ft/sec a = ft/sec2
