1.5. Automotive engineers refer to the time rate of change of acceleration as the “jerk." Assume an object moves in one dimension such that its jerk J is constant. (a) Determine expressions for its acceleration a,(t), velocity v,(t), and position x(t), given that its initial acceleration, velocity, and position are ai, Vxi, and x¡, respectively. (b) Show that = a + 2/(v,-v ).

in meters and t is in seconds. At t = 3.00 s, find (a) the position of the particle, (b) its velocity, and
(c) its acceleration.
1.2. A motorist drives south at 20.0 m/s for 3.00 min, then turns west and travels at 25.0 m/s for 2.00
min, and finally travels northwest at 30.0 m/s for 1.00 min. For this 6.00-min trip, find (a) the total
vector displacement, (b) the average speed, and (c) the average velocity. Let the positive x axis
point east.

1.3. A fish swimming in a horizontal plane has velocity V,= (4.00i+1.00j) m/s at a point in the ocean
where the position relative to a certain rock is ,= (10.0i – 4.00j)
constant acceleration for 20.0 s, its velocity is
of the acceleration of the fish? (b) What is the direction of the acceleration with respect to unit
vector i? (c) If the fish maintains constant acceleration, where is it at t =
direction is it moving?
1.4. A person walks first at a constant speed of 5.00 m/s along a straight line from point A to point B
and then back along the line from B to A at a constant speed of 3.00 m/s. (a) What is her average
speed over the entire trip? (b) What is her average velocity over the entire trip?
1.5. Automotive engineers refer to the time rate of change of acceleration as the “jerk." Assume an
object moves in one dimension such that its jerk J is constant. (a) Determine expressions for its
