Question

Is it possible to calculate an acceleration for a body which starts from rest and achieves a certain speed in the given time frame?

• A. Yes
• B. Not possible
• C. Data insufficient
• D. Formula does not exist

Answer 1

The correct option is A

Yes

Yes, it is possible to find the acceleration 'a'. We need to use the first equation of motion i.e.

v = u + at

Since, the object starts from rest u = 0, t is known and v is also known. So one can easily find acceleration 'a' in this case.

We get, v = 0 + at

or v = at

i.e. a = $\frac{v}{t}$
