To find velocity when acceleration and instant velocity are given, you can use the following equation:
Final velocity (v) = Initial velocity (u) + (acceleration (a) × time (t))
However, in this case, you have the instant velocity instead of the initial velocity. So, you need to modify the equation slightly. Let's assume the instant velocity is represented by "v0" (v sub-zero), and the final velocity is represented by "v" (v sub-1).
The modified equation becomes:
v = v0 + (a × t)
Here, "v" represents the final velocity, "v0" represents the initial velocity (in this case, the instant velocity), "a" represents acceleration, and "t" represents time.
Simply substitute the given values of instant velocity (v0) and acceleration (a) into the equation, along with the known values of time (t), and you can calculate the final velocity (v).
