Question

A bike accelerates uniformly from rest to a speed of 60m/s over a distance of 90m. Determine the acceleration of the bike.
A. 40m/s^2
B.20m/s^2
C. 22.5m/s^2
D. 9.8m/s^2
​

Answer 1

Answer:

0.712

Explanation:

Given, initial velocity, u=0m/s and final velocity v=7.10m/s 

Distance traveled  S=35.4m

If a be the acceleration.

Using formula v2−u2=2aS

(7.10)2−02=2a(35.4)

⟹ a=0.712m/s2

Answer 2

Question :-

A bike accelerates uniformly from rest to a speed of 60m/s over a distance of 90m. Determine the acceleration of the bike.

A. 40m/s^2

B.20m/s^2

C. 22.5m/s^2

D. 9.8m/s^2

Answer :-

• (b) 20m/s²

Step by step explanation :-

We have,

• Initial velocity (u) = 0m/s
• Final velocity (v) = 60m/s
• Distance (s) = 90m

We have to find,

• acceleration

Using Formula,

• v² - u² = 2as

Substituting all having values in the formula,

$\rm:\longmapsto{(60) {}^{2} - (0) {}^{2} = 2(a)(90)} \: \: \: \: \: \\ \\ \rm:\longmapsto{3600 = 180a} \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ \\ \rm:\longmapsto{a = \frac{3600}{180} } \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ \\ \bf:\longmapsto \red{acceleration = 20m /s {}^{2} }$
