Chapter 11, Problem 11.183RP
A drag racing car starts from rest and moves down the racetrack with an acceleration defined by a = 50 − 10t, where a and t are in m/s2 and seconds, respectively. After reaching a speed of 125 m/s, a parachute is deployed to help slow down the dragster. Knowing that this deceleration is defined by the relationship a = −0.02v2, where v is the velocity in m/s, determine (a) the total time from the beginning of the race until the car slows back down to 10 m/s, (b) the total distance the car travels during this time.

A body moves along a linear path and its rate of change of velocity varies with time and is written as a=2-3t, where t is the time in second. After 5 second, from start of observation its velocity is determined to be 20 m/s. After 10 second from start of observation, the body is at 85 m far from the origin. Determine the following:a. Rate of change of velocity and velocity at the start of motion.b. Distance from the origin at the start of observationc. Time after start of observation in which the velocity becomes zero.
The acceleration of a particle moving horizontally under rectilinear motion is defined by the relation a=9.4t2-4.6t where a is in ft/s2 and t is in s.
Initially, the particle is moving at 6ft/s and started at x=9.6 ft. Determine the position of the particle at t=4.4s. Round off only on the final answer expressed in 3 decimals. Indicate appropriate units.
