Chapter 6, Problem 6.35P
A motorboat cuts its engine when its speed is 10.0 m/s and then coasts to rest. The equation describing the motion of the motorboat during this period is ʋ = ʋie-a , where ʋ is tin? speed .at time t, ʋ, is the initial speed at t = 0, and r is a constant. At t = 20.0 s. the speed is 5.00 m/s. (a) Find the constant c. (b) What is the speed at t - 40.0 s? (c) Differentiate die expression for ʋ(l) and thus show that the acceleration of the boat is proportional to the speed at any time.

I was wondering how to do this problem. What equation do I need to do to answer this question? And how much do I estimate the last question?
The velocity of a particle moving along the x-axis is defined by V= kx3 – 4x2 +6x, where V is in m/sec., x is in meters, and k is a constant. If K=1 Compute the value of the acceleration after x= 2 meters.

- Very large accelerations can injure the body, especially if they last for a considerable length of time. One model used to gauge the likelihood of injury is the severity index (??), defined as ??=?^5/2?. In the expression, ?t is the duration of the acceleration, but ?a is not equal to the acceleration. Rather, ?a is a dimensionless constant that equals the number of multiples of ?g that the acceleration is equal to. In one set of studies of rear-end collisions, a person's velocity increases by 17.5 km/h17.5 km/h with an acceleration of 30.5 m/s230.5 m/s2 .
