Answer:

0.6m/s²

Explanation:

Given parameters:

Initial velocity  = 3m/s

Final velocity  = 4.5m/s

Time taken  = 2.4s

Unknown:

Average acceleration  = ?

Solution:

To solve this problem, we use the expression:

 Acceleration  = \frac{v - u}{t}  

v is the final velocity

u is the initial velocity

t is the time taken

    Acceleration  = \frac{4.5 - 3}{2.5}   = 0.6m/s²

Tall trees collapse in stoms, why?​
Sidana [21]

Answer: <em>One main reason, all three experts agree, is the phenomenon known as “windthrow” which uproots a tree. “The tree trunk acts as a lever and so the force applied to the roots and trunk increases with height,” says Foster. “Taller trees are more susceptible to windthrow.”</em>

Steve is planning his annual Spring Break road trip. He pulls out his map and draws out his route to visit the five locations th
Aleksandr [31]

Answer:

His average speed.

Explanation:

Average speed = Total distance travelled / total time .

In the given case odometer measures total distance travelled . Dividing it by time will give average speed .

Average velocity can not be the answer as it is measured by dividing displacement by time . Displacement here is zero because initial and final point are same . Instantaneous velocity is given by the speedometer . It keeps on changing all the time . It is actually speed at a particular point of time . It can not be average velocity or speed .
