In summary, a GCE OL pastpaper question refers to a previously used question on a General Certificate of Education Ordinary Level exam. These questions can be used for practice and to get an idea of the types of questions that may appear on future exams. They can also be a useful study tool for familiarizing oneself with the exam format and structure. However, they are not guaranteed to be the exact same questions on the current exam. Pastpaper questions can be found on the official exam board website or through online resources, and should be used as a supplement to other study materials. It is important to review and understand the answers to pastpaper questions to learn from any mistakes made.

A GCE OL pastpaper question...

Can someone get over this for me please...thanx ie

The velocity, v m/s, of a particle P after t seconds is given by
v = 20 + 12*t[squared] - t[cubed] , t is larger than 0.

Calculate the value of t when the acceleration of P is 0.

[tex]v(t)=20+12t^2-t^3,\;\;t>0[/tex]

[tex]We \;know:\,a(t)=v\prime(t)[/tex]

[tex]a(t)=24t-3t^2=0[/tex]

[tex]t=8\,(sec)[/tex]

To calculate the acceleration, we need to find the second derivative of the velocity function.
The second derivative is given by: a = 24 - 6t

To find when the acceleration is 0, we set the equation equal to 0 and solve for t.
0 = 24 - 6t
6t = 24
t = 24/6
t = 4

Therefore, when t is equal to 4 seconds, the acceleration of particle P is 0.
