Anastasy [175]

Answer:

97 minutes and 12 seconds

Explanation:

Let x be the total time

From the first statement

$\frac{10}{100}x=24\times 60+18\\\Rightarrow 0.1x=1458\\\Rightarrow x=\frac{1458}{0.1}\\\Rightarrow x=14580\ seconds$

Total time of Dara's exercise is 14580 seconds

40 %

$\frac{40}{100}\times 14580=5832\ seconds$

$\frac{5830}{60}=97.2\ minutes=97+0.2\times 60\\ =97\ minutes\ and\ 12\ seconds=1\ hour\ 37\ minutes\ and\ 12\ seconds$

Time when she had completed 40% was 1 hour 37 minutes and 12 seconds

Example 2.13 The acceleration a of a particle in a time t is given by the equation a = 2+ 5t^2. Find the instantaneous velocity

Serhud [2]

Answer:

the instantaneous velocity is 51 m/s

Explanation:

Given;

acceleration, a = 2 + 5t²

Acceleration is the change in velocity with time.

$a = \frac{dv}{dt} \\\\a = 2 + 5t^2\\\\The \ acceleration \ (a) \ is \ given \ so \ we \ have \ to \ find \ the \ velocity \ (v)\\\\To \ find \ the \ velocity, \ integrate\ both \ sides \ of \ the \ equation\\\\2 + 5t^2 = \frac{dv}{dt} \\\\\int\limits^3_0 {(2 + 5t^2)} \, dt = dv\\\\v = [2t + \frac{5t^3}{3} ]^3_0\\\\v = 2(3) + \frac{5(3)^3}{3} \\\\v = 6 + 5(3)^2\\\\v = 6 + 45\\\\v = 51 \ m/s$
