if the 1kg standard body an acceleration of 20.0° to the postive direction of an x axiis : a) what are the x and y compnonents of the net force acting on the body . b) what is the net force in unit-vector nation

Aregular polygon has angkes of size 150° each.how many side has the polygon

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

Why don't you see your reflection in water with waves or repples
