1. A particle is moving along a straight line such that its velocity is defined as v = (-4s³-3s) m/s, where s is in meters. If at t=0 s=3m, determine the velocity as a function of time, and determine the velocity when t-1s. (6 points) 2. The position of a particle that moves along the x-axis is defined by x--x²+121-6m, where tis in seconds. For the time interval t=0 to t-3 s, (a) plot the position, velocity, and acceleration as functions of time; (b) calculate the distance traveled; (c) determine the displacement of the particle.
