Consider a grey squirrel falling out of a tree to the ground. (a) If we ignore air resistance in this case (only for the sake of this problem), determine a squirrel's velocity just before hitting the ground, assuming it fell from a height of 3.0 m. (b) If the squirrel stops in a distance of 2.0 cm through bending its limbs, compare its deceleration with that of the airman in the previous problem.
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?
Assume that an intercontinental ballistic missile goes from rest to a suborbital speed of 6.50 km/s in 60.0 s (the actual speed and time are classified). What is its average acceleration in m/s2 and in multiples of g (9.80 m/s2)?
If the sprinter from the previous problem accelerates at that rate for 20 m, and then maintains that velocity for the remainder of the 100-m dash, what will be his time for the race?
An Olympic-class sprinter starts a race with an acceleration of 4.50 m/s2. (a) What is her speed 2.40 s later? (b) Sketch a graph of her position vs. time for this period.
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?
At a track meet, a runner runs the 100-m dash in 12 s. What was the runners average speed?
The average person passes out at an acceleration of 7g (that is, seven times the gravitational acceleration on Earth). Suppose a car is designed to accelerate at this rate. How much time would be required for the car to accelerate from rest, to 60.0 miles per hour? (The car would need rocket boosters!)
To pass a physical education class at a university, a student must run 1.0 mi in 12 min. After running for 10 min, she still has 500 yd to go. If her maximum acceleration is 0.15 m/s2, can she make it? If the answer is no, determine what acceleration she would need to be successful.
Is it possible for speed to be constant while acceleration is not zero? Give an example of such a situation.
Which is true of an object with uniform velocity? (2.2) (a) It has constant speed. (b) It has constant direction. (c) It travels equal distances in equal times. (d) All of the preceding.
A jogger jogs from one end to the other of a straight track in 2.50 min and then back to the starting point in 3.20 min. What is the joggers average speed (a) in jogging to the far end of the track, (b) coming back to the starting point, and (c) for the total jog?
