1. After traveling for 14.0 seconds, a bicyclist reaches a speed of 89 m/s. What is
the runner’s acceleration?

A=v2-v1/T2

A=6-0/14

A= 0.428

2. A car starting from rest accelerates at a rate of 18.0 m/s2​ ​. What is its final speed
at the end of 5.0 seconds?

S=D/T
S= 18.0m/s/ 5.0sec
S=3.6 sec

3. A cyclist accelerates at a rate of 16.0 m/s2​ .​ How long will it take the cyclist to
reach a speed of 49 m/s?

T= D/V
T=49m/s/16m/s
T=3.06

3. During an Apollo moon landing, reflecting panels were placed on the moon.
This allowed earth-based astronomers to shoot laser beams at the moon's surface to
determine its distance. The reflected laser beam was observed 4.6 seconds after
the laser pulse was sent. The speed of light is 3.0 ​×​ 108​ ​ m/s. What was the distance
between the astronomers and the moon?
D= V/T
D=3.0 ​×​ 108​ ​ m/s./ 4.6 s
D= 70.43 m/s2
Directions:​ Choose 4 or 5
4. It is now 10:29 a.m., but when the bell rings at 10:30 a.m. Suzette will be late for

French class for the third time this week. She must get from one side of the
school to the other by hurrying down three different hallways. She runs down
the first hallway, a distance of 65.0 m, at a speed of 5.2 m/s. The second
hallway is filled with students, and she covers its 32.0 m length at an average

speed of 1.46 m/s. The final hallway is empty, and Suzette sprints its 60.0 m
length at a speed of 7.3 m/s.

a. Does Suzette make it to class on time or does she get detention for being
late again?

T= D/v
T= 65m/5.2m/s
T=12.5 s

T=D/V
T=32m/1.46m/s
T=21.91s

T=D/v
T=60.0 m/ 7.3m/s
T=8.21s

12.5+ 21.91+8.21= 42.62
He will make it to class

5. The tortoise and the hare are in a road race to defend the honor of their breed.
The tortoise crawls the entire 1000. m distance at a speed of 0.35 m/s while the
rabbit runs the first 200.0 m at 1.85 m/s The rabbit then stops to take a nap for
1.200 hr and awakens to finish the last 800.0 m with an average speed of 4.2
m/s. Who wins the race and by how much time?

Conclusion:

The purpose of this experiment was the find the velocity for each half of the ramp.
The whole ramp was 200m so each half of the ramp is 100m. My hypnosis was the
the bottom half was going to faster because it's already building speed because it
started from the top. I didn’t think the top half was faster because it didn’t have
time to build up speed. We experimented 2 angles to see was it really true. Our first
height of the ramp was 50m and the second height was 100m. For the 50m, We
found the velocity of the first half of the ramp, which was the top half. We found
the first velocity by dividing the distance and time. It was 100/10 whic​h i got
10m/s. For the 50m it took 10 sec to go down 100 m. For the second half the
velocity was 20 sec. That makes the bottom half faster. Because It only took 5 sec
to get down. The acceleration for the 50m was 2m/s. Then we tried the 2nd angles
which was 100m. For the time half it took 5 sec to get down 100m. The velocity I
got using V=D/T was 20 sec. The bottom half surprised me. It only took 2 sec to
get down 100m. The velocity for that was 50 m/s. The acceleration for the 100m
was 15 m/s. The

EXTRA CREDIT:
Light from another star in the galaxy reaches the earth in 46 minutes. The speed of
light is 3.0 ×​ ​ 10​8​ m/s. In k​ ilometers,​ how far is the earth from the star?

Answer must be in scientific notation
