A car speeds up from 13 m/s to 23 m/s in 30 seconds. What is the acceleration of the car?
ra1l [238]
Well, <span>v = u + a×t is the equation.</span>
<span>
v: final velocity, which is 23 m/s in this equation.</span>
<span>u: initialo velocity = 13 m/s </span>
<span>a: acceleration = ? </span>
<span>t: time = 30s 
</span>
Your equation would be...

<span>23 = 13 + a×30 </span>
<span>a = (23 - 13) / 30 </span>
<span>a = 1 / 3 </span>
<span>a = 0.333 m/s</span>

tankabanditka [31]

Answer:

Explanation:

Given

Mass of alice M_a=50 kg

Mass of bob M_b=70 kg

Mass of beam M=20 kg

Suppose fulcrum is at distance of d from bob thus From diagram

Equating torque i.e. torque of Bob,Alice and beam must cancel out each other to be balanced

500\times (8-d)+20\times (4-d)=70\times d

400-50d+80-2d=70d

480=140d

d=\frac{480}{140}

d=3.43 m
