Force = Mass x Acceleration
Initial speed of car = 0, Final speed = 40 feet/sec in time 2 seconds
Acceleration = (v-u)/t = (40 - 0)/2 = 20 feet/sec/sec
Force = 3500 x 20 = 70000 pounds/sec/sec

What is your 100 meter time converted from 9.90 for 100 yards?
10.0 and 9.9 seconds is not the same thing when accuracy is needed, not rounded off numbers. 10.0 and 9.9 seconds is not the same thing when accuracy is needed, not rounded off numbers. 10.0 and 9.9 seconds is not the same thing when accuracy is needed, not rounded off numbers.
How many seconds are needed by a car whose speed is 40 km hr to cover a distance of 8 km?
12 minutes = 720 seconds
How fast would your mile be if you ran 8 miles in 4 minutes and 31 seconds?
Velocity = Distance ÷ Time. BUT : we need to ensure the measurements used are converted (if needed) to provide a sensible answer. If the answer is required in miles per hour (mph) then the distance of 8 miles is fine but the time of 4 minutes 31 seconds needs to be converted into hours. 31 seconds = 31/60 minutes = 0.516667 mins 4.516667 mins = 4.516667/60 hours = 0.075278 hours Then 8 ÷ 0.075278 = 106.27mph (2dp)
What are three components needed to find an object acceleration?
Using the definition of acceleration as change of speed / time, you basically need to know: * A time interval during which the object accelerates. * The velocity at the beginning of this time interval. * The velocity at the end of this time interval.
A weight on the end of a spring bobs up and down one complete cycle every 2 seconds its period is?
We clearly heard you say "one complete cycle every 2 seconds". That means that the period is 2 seconds. No calculation or arithmetic of any kind is needed.
What Velocity is needed to penetrate earth's atmosphere?
Simple - look up escape velocity on wikipedia
What information is needed to determine the average velocity of a marble?
All you need to know is the distance the marble travelled and how long it took to travel that distance. For example, if a marble travels 30 cm in 5 seconds then its average velocity would be 30 / 5 cm / sec = 6 cm / sec.
Is orbital velocity the velocity a rocket must reach to fly off into space?
No.Orbital Velocity is the velocity required by a body to achieve a circular orbit around its primary.Escape velocity is the minimum velocity needed to escape a gravitational field
What must be included when reporting an objects velocity-?

What is the only factor needed to calculate change in velocity due to acceleration of gravity 9.8 m s?

What is needed to measure velocity of an object?
In order to measure velocity you need displacement (a start location and an end location) and time.
What is the rate at which an object is moving at a given instant called?
speed if no direction is needed velocity if direction is needed
What is the only factor needed to calculate change in velocity due to acceleration of gravity (9.8 ms)?
