An object that is thrown straight up falls back to Earth. This is one-dimensional motion. (a) When is its velocity zero? (b) Does its velocity change direction? (c) Does the acceleration clue to gravity have the same sign on the way up as on the way clown?
Does a car's odometer measure position or displacement? Does its speedometer measure speed or velocity?
(a) Can the instantaneous velocity of an object at an instant of time ever be greater in magnitude than the average velocity over a lime interval containing that instant? (b) Can it ever be less?
Is it possible for velocity to be constant while acceleration is not zero? Explain.
A race car traveling northward on a straight, level track at a constant speed travels 0.750 km in 20.0 s. The return trip over the same track is made in 25.0 s. (a) What is the average velocity of the car in m/s for the first leg of the run? (b) What is the average velocity for the total trip?
Give an example in which velocity is zero yet acceleration is not.
An arrow is shot straight up in the air at an initial speed of 15.0 m/s. After how much time is the arrow heading downward at a speed of 8.00 m/s? (See Section 2.6.)
If an object is thrown straight up and air resistance is negligible, then its speed when it returns to the starting point is the same as when it was released. If air resistance were not negligible, how would its speed upon return compare with its initial speed? How would the maximum height to which it rises be affected?
A swan on a lake gets airborne by flapping its wings and running on top of the water. (a) If the swan must reach a velocity of 6.00 m/s2, to take off and it accelerates from rest at an average rate of 0.350 m/s2, how far will it travel before becoming airborne? (b) How long does this take?
A motorboat starting from rest travels in a straight line on a lake. (a) If the boat achieves a speed of 8.0 m/s in 10 s, what is the boats average acceleration? (b) Then, in 5.0 more seconds, the boats speed is 12 m/s. What is the boats average acceleration for the total time?
