Question

A boy walks a distance of 100 meters to the right at a steady speed of 1.00 m/s. Then he stops for 30 seconds. Then returns back and walks for 2 minutes to the left at speed of 1.5m/s.

- Calculate the total time of his round trip.

- Calculate the total distance.

- Calculate the total displacement.

- Calculate the average speed.

Calculate the average velocity

Answer #1

A boy runs for 2 minutes to the right at speed of 2.0 m/s. Then
he stops for 1.0 minute. Then runs 100 m to the left at speed of
1.5 m/s.
a) Calculate the total time of his round trip in
seconds. (show complete solution).
b) Calculate the total distance in meters(m). show formula
first.
c) Calculate the total displacement I meters(m). show formula
first.
d) Calculate the average speed in m/s. show formula first.
e) Calculate the average...

A man walks 273 north in 195 s, then turns west and accelerates
in 2.6 s from his previous speed to a running speed of 3.14 m/s. If
he then runs west at this speed for 10 minutes, find this average
velocity (magnitude and direction) for the whole trip. Please
provide all work/formula.

A man sprints in a straight line for 50.0 m in 10.0 s, and then
walks slowly back to the starting line in 50.0 s. The “sprint
direction” is taken to be positive. Match the answer choices with
the proper average velocity or speed.
- A.
B. C.
D.
What is the average sprint velocity ?
- A.
B. C.

A river has a steady speed of 0.474 m/s. A student swims
upstream a distance of 1.00 km and swims back to the starting
point.
(a) If the student can swim at a speed of 1.18 m/s in still
water, how long does the trip take?
(b) How much time is required in still water for the same length
swim?
(c) Intuitively, why does the swim take longer when there is a
current?

A salesman drives from Ajax to Barrington, a distance of 120 mi,
at a steady speed. He then increases his speed by 18 mi/h to drive
the 169 mi from Barrington to Collins. If the second leg of his
trip took 10 min more time than the first leg, how fast was he
driving between Ajax and Barrington?
I've been stuck on this for hours. I keep getting a decimal
under the radicand and it's driving me crazy please help.

A
boat traveled downstream a distance of 24 miles and then came right
back. If the speed of the current was 6 mph and the total trip took
3 hours, find the average speed of the boat relative to the
water.

A dog walks for 10 minutes 800 m toward the east direction along
a deserted road. Looking for his dog, his owner drives a car, finds
him and takes the dog back to his house, 1.8 Km to the west
direction with an average speed of 10 m/s. What is the magnitude of
the average velocity of the dog for its entire journey.

An object object travels 31 meters in the +x direction for 3.2
seconds, and then immediately travels some distance in the -x
direction. After a total time of 7.7 seconds, the object's average
velocity is 0 m/s. What is the average velocity for the second part
of the trip (traveling in the -x direction) in m/s? If in the
negative x direction, indicate so with a negative sign.
PLEASE SHOW WORK!!!!

A boat traveled downstream a distance of 36 mi and then came
right back. If the speed of the current was 12 mph and the total
trip took 4 hourscomma nbsp, find the average speed of the boat
relative to the water.
The boat had an average speed of ____________ mph relative to
the water.
