A dog runs at 21 km/h [N] for 5.0 min, slows to a stop over a period of 8.0 s, sniffs at a tree for 2.0 min, and then takes off, starting with an acceleration of 1.0 m/s2 [E] until it reaches a velocity of 3.5 m/s [E], at which it continues for 3.0 min. What was its average velocity for this entire time period?

(a) If its original velocity is 5.90 m/s, what is its displacement (in m) during the time interval? m (b) What is the distance it travels (in m) during this interval? (c) A second body moves in one dimension, also with a constant acceleration of 4.65 m/s , but over some different time interval. Like the first body, its velocity at the end of the interval is 11.8 m/s, but its initial velocity is -5.90 m/s. What is the displacement (in m) of the secorkd body over this interval? (d) What is the total distance traveled (in m) by the second body in part (c), during the interval in part (c)? m

Suppose a cyclist is going 20m/s (44mph) at the end of a race, and begins coasting after crossing the finish line. The coasting cyclist has a velocity-dependent acceleration (in the x-direction) given by ag = -(0.01lm-1)v², which is negative because they are slowing. Ignoring time, find how far the cyclist will have traveled beyond the finish line when they are rolling at a speed of 10m/s.
An airplane starts its takeoff by moving at 2.6 m/s. The plane must then accelerate at 3.0 m/s2 for the next [t] 30 s to reach its final takeoff speed. To the nearest tenth of a kilometer, how far does the plane travel while accelerating to its takeoff speed?

The velocity of a particle traveling in a straight line is given by v = (6t – 3t²) m/s, where t is in seconds. If s = 0 when t = 0, determine the particle's deceleration and position when t = 5 s. How far has the particle traveled during the t = 5 s time interval, and what is its average speed? I need a clear answer by hand, not by keyboard | dybala
