What is acceleration for the first 10 seconds? Use that a to find the speed of the particle when t = 10 seconds, v(t=10)? b) What is the position of the of the particle when t = 10 sec,
x(t=10)?
c) From 10 to 15 seconds, what is a? So what is v?
d) How far does the particle move between 10-15 seconds?
e) From 15 to 20 seconds, how far does the particle move?
f) What is the speed when t = 20 sec?

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
