I presume that you mean 'An object travelling initally at 10m/s, accelerates at 4m/s2 for 8s; what is its final speed? If it is accelerating at 4 m/s2, it gains 4m/s every s v= u + at where v is the final speed, u is the initial speed, a is the acceleration and t is the time v = 10 + 4(8)= 42 m/s

What is the frequency if the period was 4 seconds?
Frequency = (1)/(period) .If the period is still 4 seconds, then the frequency = (1)/(4 seconds) = 0.25 per second = 0.25 Hz.
The unit used to measure period is the .?
second
An object that completes 100 vibrations in 5 seconds has a period of?
It completes 20 vibrations per second, the the period is 1/20 of a second.
How many seconds have passed when the second hand is at 4?
If the second hand began at 12, 1200 seconds would pass in this period, or 20 minutes.
If a planes initial speed is 0 meters per second and is accelerated at 15 meters per second squared what is its speed for 0-10?
The plane's velocity at 10 seconds will be 150 meters per second or 335.54 mph
Is motion of a balloon ascending at a rate of 14 meter per second is accelerated or decelerated?
since the balloon is moving up with a constant speed it is not accelerated or decelerated
What is the frequency if the period was 4 seconds?
Frequency = (1)/(period) .If the period is still 4 seconds, then the frequency = (1)/(4 seconds) = 0.25 per second = 0.25 Hz.
The unit used to measure period is the .?
second
What is the timeperiod of pendulum which ticks seconds?
The period is 1 second.
What will the time period of 500 vibrations per second?
It will be 1/500 of a second = 0.002 seconds.
An object that completes 100 vibrations in 5 seconds has a period of?
It completes 20 vibrations per second, the the period is 1/20 of a second.
What is the period of a wave traviling 5 ms it its wavelength is 20 m?
If a wave is traveling at 5 meters per second (assuming that is what the question meant) and its wavelength is 20 meters, consider standing beside the wave and watching it pass. As the wave is 20 meters long and it is moving at 5 meters per second, it will take 4 seconds for the full cycle of the wave to pass an observer. That means its frequency is one cycle per 4 seconds. And - surprise! - that's the period of the wave. The period of the wave is 4 seconds.
A car accelerates from rest at 2 meters per second per second What is its speed 3 seconds after the car starts moving?
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.
What are the risk of skipped beats and accelerated heartrate?
A skipped beat is a beat that is not in rhythm (the 2-second rhythm) whereas an accelerated heartbeat is that heartbeat that happens before the 2 seconds interval elapses, and both are a risk to the normal operation of the heart.
How many seconds have passed when the second hand is at 4?
If the second hand began at 12, 1200 seconds would pass in this period, or 20 minutes.
How many type of seconds are there?
there was one kind of second. it is called nanoseconds. Usually, it can be seen faster moving than a second in a timer.
If a planes initial speed is 0 meters per second and is accelerated at 15 meters per second squared what is its speed for 0-10?
The plane's velocity at 10 seconds will be 150 meters per second or 335.54 mph
