A parcel of air moving in a straight tube with a constant acceleration of -4.00 m/s2 has a velocity of 13.0m/s at 10:05:01 a.m? (a)What is its velocity at 10:05:01a.m?
(b) At 10:05:04 a.m.?
(c) At 10:04:50 a.m?
(d) Describe the shape of a graph of velocity versus time for this parcel of air.
(e) Argue for or against the following statement:" Knowing the single value of an object's constant acceleration is like knowing a whole list of values for its velocity".
The acceleration of an object (in m/s2) is given by the function a(t)=7sin(t)a(t)=7sin(t). The initial velocity of the object is v(0)=−1v(0)=-1 m/s. Round your answers to four decimal places.
v(t) = -7cos(t) + 6
The objects displacement from time 0 to 3 is: 17.01216 meters
Find the total distance traveled by the object from time 0 to time 3.
