Homework Help: physics

Posted by Kaylah on Friday, October 14, 2011 at 8:13pm.

A particle leaves the origin with an initial velocity = (2.35 m/s) and moves with constant acceleration = (-1.90 m/s2) + (2.60 m/s2)>.
(a) How far does the particle move in the x direction before turning around?
m

(b) What is the particle's velocity at this time?
( m/s) + ( m/s)

(c) Determine the particle's position x at t = 0.500 s, 1.00 s, 1.50 s, and 2.00 s.
x(0.500 s) = ( m) + ( m)
x(1.00 s) = ( m) + ( m)
x(1.50 s) = ( m) + ( m)
x(2.00 s) = ( m) + ( m)
Plot these points, and use them to sketch position versus time for the particle.
