Sketch a position-time graph for a bear starting

Physics
1 answer:
Dmitrij [34]3 years ago
3 0

Explanation:

hopefully that makes sense. the position doesn't change over the 5 seconds, meaning it's stopped but time still continues. then when the slope is negative this shows the bear's position becoming negative (backing up, changing direction).

A particle moving in a straight line with a constant acceleration covers 10m in 2 seconds and 22m in a further 2 seconds. How mu
MrRissso [65]

The particle will travel  a distance of 28 m in the next two seconds

<h3>Acceleration</h3>

Acceleration is defined as the change in velocity with time

  • Acceleration = final velocity - initial velocity / time
<h3>Calculating initial velocity</h3>

distance covered = 10 m

time = 2 seconds

velocity = distance/time

initial velocity = 10/2

initial velocity = 5m/s

<h3>Calculating final velocity</h3>

distance = 22 m

time = 2 seconds

Final velocity = 22/2

Final velocity = 11 m/s

<h3>Calculating acceleration</h3>

Acceleration = change in velocity/time

acceleration = 11m/s - 5m/s /2 s

acceleration = 3m/s²

<h3>Calculating distance covered</h3>

Using the equation of motion:

s = ut + at²/2

s = 11 * 2 + 3 * 2²/2

s -=28 m

Therefore, the particle will travel  a distance of 28 m in the next two seconds
