The average acceleration will be "7 m/s²".

Given values:

Top velocity,

v = 1 m/s

Bottom velocity,

u = 36 m/s

Time,

t = 5 s

The acceleration is:

→ $A = \frac{v -u}{t}$

By putting the values,

$= \frac{36-1}{5}$

$= \frac{35}{5}$

$= 7 \ m/s^2$

Thus the answer above i.e., "option d" is correct.

Answer from: kittybatch345

7m/s²

Explanation:

Given parameters:

Velocity at the top = 1m/s

Velocity at the bottom = 36m/s

Time = 5s

Unknown:

Average acceleration = ?

Solution;

Acceleration is the rate of change of velocity with time. It is expressed as;

A = $\frac{v -u}{t}$

v is the velocity at the top

u is the velocity at the bottom

t is the time taken

Now, insert the parameters and solve;

A = $\frac{36 - 1}{5}$ = 7m/s²

A roller coaster is travelling 1 m/s at the top of the track. At the bottom of the track, 5 seconds

Answer from: Quest

this is an example of "committed" time.

committed time, as contracted time, takes need over essential and available time since it is seen as profitable work. it alludes to the time allotted to keep up a home and family. at the point when a man is commuting using committed time this individual may feel that the drive is an obligation to family, for example, strolling youngsters to class or driving a mate to work. contracted and committed time clients may feel that their commute could really compare to the commute of important or leisure time clients on the grounds that their commute is profitable work. in this manner, they might be more disposed to pick a mechanized method of movement.

Answer(a) the matererials that are in contact, the two materials and the nature of their surfaces/// (b)/// the force pushing the two surfaces together, pushing the surfaces together causes the more of the asperities to come together and increases the surface area in contact with each other
