Chapter 4: Q118P (page 92)

An airport terminal has a moving sidewalk to speed passengers through a long corridor. Larry does not use the moving sidewalk; he takes 150s to walk through the corridor. Curly, who simply stands on the moving sidewalk, covers the same distance in 70s. Moe boards the sidewalk and walks along it. How long does Moe take to move through the corridor? Assume that Larry and Moe walk at the same speed.

Short Answer

Expert verified

Time to move through the corridor is48s

Step by step solution

01

Given information

t1=150st2=70s

02

Determining the concept

Use basic definition of velocity to find the answer of the given problem. Velocity is total displacement divided by time.

Formula:

v=dt (i)

Where, d is total displacements, v is an initial velocity and t is time.

03

Determining the time to move through the corridor

Now,

Using equation (i), the time can be written as,

t1=dv1

and

t2=dv2

Total time T is given as,

T=dV1+V2

Now, plug the values of v1and v2,

T=ddt1+dt2

So,

T=11t1+1t2

T=11150+170

So,T=48s

A track meet is held on a planet in a distant solar system. A shot-putter releases a shot at a point 2.0mabove ground level. A stroboscopic plot of the position of the shot is shown in Fig. 4-61, where the readings areapart and the shot is released at time t = 0. (a) What is the initial velocity of the shot in unit-vector notation? (b) What is the magnitude of the free-fall acceleration on the planet? (c) How long after it is released does the shot reach the ground? (d) If an identical throw of the shot is made on the surface of Earth, how long after it is released does it reach the ground?

A baseball is hit at Fenway Park in Boston at a point 0.762 mabove home plate with an initial velocity of 33.53 m/sdirected 55.0°above the horizontal. The ball is observed to clear the 11.28-m-high wall in left field (known as the “green monster”)5.00 s after it is hit, at a point just inside the left-field foulline pole. Find (a) the horizontal distance down the left-field foul line from home plate to the wall; (b) the vertical distance by which the ball clears the wall; (c) the horizontal and vertical displacements of the ball with respect to home plate 0.500 sbefore it clears the wall.

A golf ball is struck at ground level. The speed of the golf ball as a function of the time is shown in Figure, wheret=0at the instant the ball is struck. The scaling on the vertical axis is set byva=19m/sandvb=31m/s. (a) How far does the golf ball travel horizontally before returning to ground level? (b) What is the maximum height above ground level attained by the ball?

For women’s volleyball the top of the net is 2.24above the floor and the court measures 9.0mby 9.0 m on each side of the net. Using a jump serve, a player strikes the ball at a point that is 3.0m above the floor and a horizontal distance of 8.0m from the net. If the initial velocity of the ball is horizontal, (a) what minimum magnitude must it have if the ball is to clear the net and (b) what maximum magnitude can it have if the ball is to strike the floor inside the back line on the other side of the net?

A small ball rolls horizontally off the edge of a tabletop that is1.20m high. It strikes the floor at a point1.52m horizontally from the table edge. (a)How long is the ball in the air? (b)What is its speed at the instant it leaves the table?
