Let's say that an object has a small, but constant acceleration in a straight line without changing direction. The object does not turn and is only moving forward (so no veering left right etc) and keeps going faster and faster. How would you describe the change in velocity from 1 to 2 seconds, compared to change in velocity from 5 to 6 seconds?
Find an expression for the velocity function, v(t), of an object moving in a straight line...
Find an expression for the velocity function, v(t), of an object moving in a straight line if the object's acceleration function is 7 sin(t) +0.06 and the object's initial velocity is 155 ft/s. Then use your function to determine the object's velocity after 28 seconds.
The figure shows the velocity of an object moving along a straight line as a function of time. Determine:
