Chapter 3: Q16. (page 67)

At what point in its path does a projectile have the least speed?

Short Answer

Expert verified

A projectile has the least speed at the top of its path.

Step by step solution

01

Step 1. Projectile motion

In problems related to projectile motion, you should consider a time interval for which the body is in the air because of the influence of gravity.

Also, the throwing process is not considered in projectile motion.

02

Step 2. Determine the point at which the projectile has the lowest speed

When the projectile is at the top of the path, its speed is the lowest. At the top, the vertical speed is equivalent to zero. If the effects of air resistance are neglected in a projectile motion, the horizontal speed will remain constant throughout the motion.

Thus, at the top of its path, a projectile has the least speed.

You are on the street trying to hit a friend in his dorm window with a water balloon. He has a similar idea and is aiming at you with his water balloon. You aim straight at each other and throw at the same instant. Do the water balloons hit each other? Explain why or why not.

A child, who is 45 m from the bank of a river, is being carried helplessly downstream by the river’s swift current of 1.0 m/s. As the child passes a lifeguard on the river’s bank, the lifeguard starts swimming in a straight line (Fig. 3-46) until she reaches the child at a point downstream. If the lifeguard can swim at a speed of 2.0 m/s relative to the water, how long does it take her to reach the child? How far downstream does the lifeguard intercept the child?

A diver leaves the end of a 4.0-m-high diving board and strikes the water 1.3 s later, 3.0 m beyond the end of the board. Considering the diver as a particle, determine: (a) her initial velocity,v→0, (b) the maximum height reached; and (c) the velocityv→fwith which she enters the water.
