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.

A person going for a morning jog on the deck of a cruise ship is running toward the bow (front) of the ship at 2.0 m/s while the ship is moving ahead at 8.5 m/s. What is the velocity of the jogger relative to the water? Later, the jogger is moving toward the stern (rear) of the ship. What is the jogger鈥檚 velocity relative to the water now?

Extreme-sports enthusiasts have been known to jump off the top of El Captain, a sheer granite cliff of height 910 m in Yosemite National Park. Assume a jumper runs horizontally off the top of El Captain with speed4.0m/sand enjoys a free fall until she is 150 m above the valley floor, at which time she opens her parachute (Fig. 3-37). (a) How long is the jumper in free fall? Ignore air-resistance. (b) It is important to be as far away from the cliff as possible before opening the parachute. How far from the cliff is this jumper when she opens her chute?

A baseball is hit with a speed of27.0m/sat an angle of45.0o. It lands on the flat roof of a 13.0 m tall nearby building. If the ball was hit when it was 1.0 m above the ground, what horizontal distance does it travel before it lands on the building?
