1. (150 meters) / (18 seconds) = 8.33 meters per second
2. total distance = 4 + 2 + 1 = 7 kilometers
total time = 32 + 22 + 16 = 70 minutes
average speed = 7/70 = 0.1 kilometer per minute
3. (120 kilometers) / (2 hours and 30 minutes) = 120 / 2.5 = 48 kilometers per hour
4. (600 km/hr) x (2.5 hrs) = 1500 kilometers
5. total distance = 750 + 250 = 1000 meters
total time = 13 seconds??? (or should this be in minutes, because he can't be that fast ?)
If time = 13 seconds:
speed = 1000 / 13 = 76.92 meters per second
If time = 13 minutes
speed = 1000 / (13 x 60) = 1000 / 780 = 1.28 meters per second
6. Acceleration = (change in velocity) / time
= ( v2 - v1 ) / t
= ( 26 - 10 ) / 2
= 16 / 2
Acceleration = 8 meters per second squared = 8 m/s^2
1.  (150 meters) / (18 seconds) = 8.33 meters per second

2.  total distance = 4 + 2 + 1 = 7 kilometers
total time = 32 + 22 + 16 = 70 minutes
average speed = 7/70 = 0.1 kilometer per minute

3.  (120 kilometers) / (2 hours and 30 minutes) = 120 / 2.5 = 48 kilometers per hour

4.  (600 km/hr) x (2.5 hrs) = 1500 kilometers

5.  total distance = 750 + 250 = 1000 meters
total time = 13  seconds??? (or should this be in minutes, because he can't be that fast ?)

If time = 13 seconds:
speed = 1000 / 13 = 76.92 meters per second

If time = 13 minutes
speed = 1000 / (13 x 60) = 1000 / 780 = 1.28 meters per second

6.  Acceleration = (change in velocity) / time
=  ( v2 - v1 ) / t
=  ( 26 - 10 ) / 2
= 16 / 2
Acceleration  =  8 meters per second squared  =  8 m/s^2

Acceleration is equal to

the change in velocity

the time to accomplish that

.

That method of explaining acceleration can be obtained from the basic kinematic formula (using the suvat variables)

v

=

u

+

a

t

.

Rearranging the variables as follows

a

t

=

v

u

a

=

v

u

t

That is equivalent to the explanation I gave you in words.

Therefore,

a

=

26

8 m/s^2

Explanation:

The formula for acceleration is a = (Vf / Vi)/t

Whereas:

a = Acceleration

Vf = Final Velocity

Vi = Initial Velocity

t = time

Given:

Vf = 26m/s

Vi = 10m/s

t = 2s

By Substituiting the values we will get:

a = (26-10)/2

a = 8 m/s^2

Hope it helps :)
