anastassius [24]

<h2>Answer:-</h2>

$\pink{\bigstar}$ The acceleration of the wheelchair is $\large\leadsto\boxed{\tt\purple{0.5625 \: m/s^2}}$

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

<h3>• Given:-</h3>

Initial velocity of the wheelchair = 0 m/s

Final velocity of the wheelchair = 1.5 m/s

Distance covered by the wheelchair = 2 m

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

Acceleration of the wheelchair = ?

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

<h3>• Solution:-</h3>

We know,

• Third Equation of Motion:-

$\pink{\bigstar}$ $\large\underline{\boxed{\bf\green{v^2 - u^2 = 2as}}}$

where,

u = Initial velocity

v = Final velocity

a = Acceleration

s = Distance covered

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

• Substituting the values in the Formula:-

➪ $\sf (1.5)^2 - (0)^2 = 2 \times a \times 2$

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

➪ $\sf 2.25 - 0 = 4 \times a$

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

➪ $\sf 2.25 = 4 \times a$

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

➪ $\sf a = \dfrac{2.25}{4}$

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

★ $\large{\bold\red{a = 0.5625 \: m/s^2}}$

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

Therefore, the acceleration of the wheelchair is 0.5625 m/s².

A bicycle starts at 2.5m/s and accelerates along a straight path to a speed of 12.5m/s in a time of 4.5 seconds. What is the bic

zalisa [80]

Answer:

The bicyclist's acceleration is 2.2m/s^2

Explanation:

Given

$u = 2.5m/s$ ---- Initial Velocity

$v = 12.5m/s$ ---- Final Velocity

$t = 4.5s$ ---- Time

Required

Determine the acceleration

This will be solved using the first equation of motion

$v = u + at$

Substitute values for v, u and a

$12.5 = 2.5 + a * 4.5$

$12.5 = 2.5 + 4.5a$

Collect Like Terms

$4.5a = 12.5 - 2.5$

$4.5a = 10.0$

Solve for a

$a = 10.0/4.5$

$a = 2.2m/s^2$ ---- (approximated)

Hence, the bicyclist's acceleration is 2.2m/s^2
