S for 0 to 2s = 20m
From 2s to 2.5s, I integrated v with limits 2.5 and 2 and got s=8.875m
So total distance would be 28.9m but the textbook ans is 29.9m. Iam not able to get 29.9 m
Thanks so much!skeeter said:well depth = $\displaystyle 20 + \int_0^{0.5} 20-t \, dt$
try again
Mechanics is a branch of physics that deals with the study of motion and the forces that cause it.
General motion in a straight line refers to the movement of an object along a straight path, where its velocity and acceleration can change over time.
Speed is a measure of how fast an object is moving, while velocity is a measure of both speed and direction of motion.
Acceleration is the rate of change of velocity over time. It can be positive (speeding up), negative (slowing down), or zero (constant velocity).
The equations used to calculate motion in a straight line are the equations of motion, which include: displacement = initial velocity x time + 1/2 x acceleration x time^2, final velocity = initial velocity + acceleration x time, and average velocity = (initial velocity + final velocity)/2.
