Initial speed is the original, beginning speed of an object.
Its initial speed is less than its final speed.
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!
Bob sed Shirley's initial speed is eight million mph
Yes.
If a car is speeding up, it's initial speed is LOWER than it's final speed.
Average speed = 1/2 (initial speed + final speed) Time = (distance)/(average speed)
I think its initial speed
Yes.
2 m/s
To orbit the Earth, a speed of 7.9 kilometers/second is required. To escape Earth's gravity, an initial speed of 11.2 kilometers/second is required. To travel to distant planets, the initial speed must be still higher.
v1 = initial velocity v2 = final velocity
