Q1) The acceleration of a particle as it moves along a straight line is given by a = (2¢- 1) m/s*, where t is in seconds. If s = I m and v = 2 m/s when ¢ = 0, determine the particle's velocity and position when 7 = 6 s. Also, determine the total distance the particle travels during this time period. Q2) The position of a particle along a straight line is given by s = (1.5f - 13.5¢ + 22.5¢) ft, where t is in seconds. Determine the position, velocity, and acceleration of the particle when t = 6 s and the total distance it travels during the 6-s time interval Q3) The acceleration of a particle traveling along a straight line is a = (8 - 25) m/s’, where s is in meters. I v = 0 at s = 0, determine the velocity of the particle at s = 2 m, and the position of the particle when the velocity is maximum Q4) A particle is moving along a straight line such that its speed is defined as v = ( -4s?) m/s, where s is in meters.

An auto accelerates forward from 7.0 m/s at a uniform 0.71 m/s2. It travels a distance of 1.033 km while accelerating. (a) How fast is the auto moving just as it is traveled the 1.033 km? Explain (b) How many seconds did it take to travel the 1.033 km?
53) While entering a freeway, a car accelerates from rest at a rate of 2.40 m/s2 for 12.0 s. (a) Draw a sketch of the situation. (b) List the knowns in this problem. (c) How far does the car travel in those 12.0 s? To solve this part, first identify the unknown, then indicate how you chose the appropriate equation to solve for it. After choosing the equation, show your steps in solving for the unknown, check your units, and discuss whether the answer is reasonable. (d) What is the car’s final velocity? Solve for this unknown in the same manner as in (c), showing all steps explicitly.
