Chapter 2, Problem 94P

An object’s acceleration increases quadratically with time; a(t) = bt2, where b = 0.041 m/s4. If the object starts from rest, how far does it travel in 6.3 s?

The position of an object is given by x = at3 - bt2 + ct,where a = 4.1 m/s3, b = 2.2 m/s2, c = 1.7 m/s, and x and t are in SI units. What is the instantaneous acceleration of the object when t = 3.5 s?
A fishing boat starts from rest and has a constant acceleration. In a certain time interval, its displacement doubles. In the same time interval, by what factor does its velocity increase? (a) 0.500, (b) 0.707, (c) 1.41, (d) 2.00, (e) 4.00.
The acceleration of a bus is given by ax(t) = αt, where α = 1.15 m/s3 is a constant. a. If the bus's velocity at time t1 = 1.05 s is 4.90 m/s, what is its velocity at time t2 = 2.20 s? b. If the bus's position at time t1 = 1.05 s is 6.05 m, what is its position at time t2 = 2.20 s?
