Want this question answered?
a few things missing: - How fast is the acceleration? - How long does it take to go from 4ms to 20ms?
Average speed = (250 / 5) = 50 meters per second.Initial speed = 0Final speed = 100 m/sAcceleration = (100 / 5) = 20 m/s2===> Must be a rocket-propelled ball; its acceleration is 2G !
distance = 1/2 acceleration x time squared; acceleration is 7 m/s/s
When a vehicle starts from rest, you may experience a slight jolt or movement as the engine engages and the vehicle begins to move forward. You may also hear the engine revving as it builds up power to propel the vehicle. Additionally, you may feel a gradual increase in speed as the vehicle accelerates.
the final velocity = initial velocity + acceleration x time; since acceleration is negative final velocity = 45 - 10x3 = 45 -30 = 15 mph
60.912 meters in that time
160 m
Unknown: final velocity, vfKnown:initial velocity, vi = 0m/stime, t = 15.0saverage acceleration, a = 2.40m/s2Equation:vf = vi + atSolution:vf = 0 + 2.40m/s2 x 15.0s = 36.0m/s

I assume the object starts from rest. The speed will be 16*3 which is 48m/s
6 meters per second. Explanation: After 1 second = 2 meters per second. After 2 seconds = 4 meters per second. After 3 seconds = 6 meters per second.
the final velocity = initial velocity + acceleration x time; since acceleration is negative final velocity = 45 - 10x3 = 45 -30 = 15 mph

No, it starts on the international date line
Fishing tends to start out slow, then accelerates quickly through the month of August.
