Chapter 2: Q1PE (page 82)

Find the following for path A in Figure 2.59:

(a) The distance travelled.

(b) The magnitude of the displacement from start to finish.

(c) The displacement from start to finish.

Short Answer

Expert verified
  1. 6 m
  2. 6
  3. +6 m

Step by step solution

01

Distance and displacement

The distance is the total length of the path covered by the body. Its unit is a meter. It is a scalar quantity.

Displacement is the shortest length from the initial and final position.

It is a vector quantity. It is measured by unit m.

If the path is a straight line, only then the distance and displacement will be equal.

02

For particle A, distance and displacement

Path of particle A

  1. The distance traveled by particle A is 6meters.
  2. The magnitude of the displacement, in this case, will be the same as the distance as it is a straight path which is6meters.
  3. The direction of the displacement would be +6m

A student writes, “A bird that is diving for prey has a speed of −10 m/s.” What is wrong with the student’s statement? What has the student actually described? Explain.

A basketball referee tosses the ball straight up for the starting tip-off. At what velocity must a basketball player leave the ground to rise above the floor in an attempt to get the ball?

A steel ball is dropped onto a hard floor from a height of 1.50 m and rebounds to a height of 1.45 m. (a) Calculate its velocity just before it strikes the floor. (b) Calculate its velocity just after it leaves the floor on its way back up. (c) Calculate its acceleration during contact with the floor if that contact lasts 0.0800 ms (\({\bf{8}}{\bf{.00 \times 1}}{{\bf{0}}^{{\bf{ - 5}}}}\;{\bf{s}}\)) . (d) How much did the ball compress during its collision with the floor, assuming the floor is absolutely rigid?

Find the following for path C in Figure 2.59:

(a) The distance travelled.

(b) The magnitude of the displacement from start to finish.

(c) The displacement from start to finish.

Dr. John Paul Stapp was U.S. Air Force officer who studied the effects of extreme deceleration on the human body. On December 10, 1954, Stapp rode a rocket sled, accelerating from rest to a top speed of 282 m/s (1015 km/h) in 5.00 s, and was brought jarringly back to rest in only 1.40 s. Calculate his (a) acceleration and (b) deceleration. Express each in multiples of g (\({\bf{9}}{\bf{.80}}\;{\bf{m/}}{{\bf{s}}^{\bf{2}}}\) ) by taking its ratio to the acceleration of gravity.
