Given F1+F2= 16 N and F1+F2 = 8 N and F1+F, is perpendicular to smaller force, then the
individual forces are :
(a) 6 N and 10 N
4 N and 12 N
(C. P.M. T. 1997)
(b) 8 N and 8 N
(d) 2 N and 14 N.

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

Find v(t), given acceleration a(t)=7j and initial velocity v(0)=k

Tall pacific coast redwood trees can reach heights of about 100 m. if air drag is negligibly small, how fast is a sequola cone moving when it reaches the ground f it dropped from the top of a 100 m tree?
