Question

1. If a man ran at 1 m/s for 10 s and then -1 m/s for 10 s more.
**Show calculations. 10 pts**

What would be the total distance he traveled? ______________ m

What would be his average speed? ______________ m/s

What was his displacement at the end of his trip? ______________ m

What was his average velocity? ______________ m/s and direction ____________

Answer #1

**1)**

**Total distance travelled = 10*1 + |10*(-1)|**

**= 10 + 10**

**= 20 m
<<<<<<<<<-----------------------Answer**

**his average speed = total distance travelled/total time
taken**

**= 20/20**

**= 1 m/s
<<<<<<<<<-----------------------Answer**

**his displacement = 10*1 + 10*(-1)**

**= 0 m
<<<<<<<<<-----------------------Answer**

**his average velocity = total displacement/total time
taken**

**= 0/20**

**= 0 m/s
<<<<<<<<<-----------------------Answer**

**Note : distance travelled is always positive. but
displacement can be positove or negative.**

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 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
man walked 440m [50.0 degrees] (polar positive) and then 580m [185
degrees] (polar positive). The entire trip took 150.0 min.
a) What was the total distance travelled?
b) What was the displacement of the man?
c) What was the average speed pf the man (in m/min)?
d) What was the average velocity of the man (in m/min)?
Could you please show me your work to these answers?
Thank you in advance:)

A river flows due south with a speed of 3.50 m/s. A man steers a

Part A.) What is the magnitude of his velocity relative to the
earth?
Part B.) What is the direction of his velocity relative to the
earth?
Part C.) How much time is required for the man to cross the
river?
Part D.) How far...

A jogger ran for 15 minutes at 4 mph in the direction 50 degrees
South of West. Then she stopped, turned to the East, and ran with a
constant acceleration of 0.2 m/s^2 for 1.0 minutes. She stopped
again, turned, and ran back to the gym with a constant velocity. In
all, she spent 40 minutes running and jogging.
a) What was her velocity (Magnitude and Direction) as she was
running back to the gym?
b)Write the vector of the...
