Its initial speed cannot be 20 m, as stated in the question. Secondly, if the initial speed is correctly given, then there is no need to calculate it!
Yes.
If you know the initial speed (u), acceleration (a) and time (t), then the final speed, v = u + at.
True
This is imposible to calculate. In order to find acceleration, knowlege of at least 3 of these variables must be given: initial speed, final speed, distance, and time.
To calculate initial speed (also known as initial velocity), use the following formula: initial speed = (final speed - acceleration*time). You will need to know the final speed, acceleration, and time to calculate the initial speed accurately.

Yes.
Without time given, it is not possible to calculate the initial speed. The initial speed can be determined only if you have the time taken to reach a certain point from rest, along with the distance traveled or acceleration information. The formula to calculate initial speed is v = u + at, where v is the final velocity, u is the initial velocity, a is acceleration, and t is time.
You can find the final speed using the formula: final speed = initial speed + (acceleration * time). Simply plug in the values for initial speed, acceleration, and time to calculate the final speed of the object.
If you know the initial speed (u), acceleration (a) and time (t), then the final speed, v = u + at.
True
Final speed of an object can be calculated using the equation: final speed = initial speed + (acceleration * time). This equation takes into account the initial speed of the object, the acceleration it experiences, and the time over which the acceleration occurs.
You can calculate the initial speed of an object by using the formula: initial speed = distance/time. This formula takes into account the distance the object travels and the time it takes to travel that distance.
False. To calculate the acceleration of an automobile, you must divide the change in velocity (final speed minus initial speed) by the time taken to achieve that change in velocity. This change in velocity can be positive or negative, depending on whether the automobile is accelerating or decelerating.
initial speed means first
Initial speed is the original, beginning speed of an object.
