fROM nEWTON'S 2ND LAW,
F = ma where m = mass and a = acceleration
F = 6000 x 2.2 = 13,200 kg-m/sec2 = 13200 Newtons
m/s(squared)

72 km per hour = 20 ms-1 108 km per hour = 30 ms-1 so acceleration = (30-20)/5 = 2ms-2 Then Force = Mass*Acceleration = 1000 kg * 2 ms-2 = 2,000 Newtons or 2 kN.
Convert inches to feet6 inches = 1/2 feetso it is a 16 x 0.5 foot board. Thus, the area of a board is16*0.5 = 8 feet squared.The number of 8 feet squared boards needed to cover 800 squared feet is800 squared feet/8 squared feet = 100

In SI units: Force in N (Newton = kg ms/s2); Acceleration in m/s2Other systems of measurement:In cgs units: Force in dyn (Dyne = g cm/s2); Acceleration in cm/s2Also force is stated in kp (kilopond or kilogram-force) - the force exerted by earth's gravity on 1 kg.In Imperial units: Force in lbf (pound-force) - the force exerted on earth's gravity on 1 lb.and in pdl (poundal = lb ft/s2); Acceleration in ft/s2
Force is defined as mass times acceleration. The unit of force is the Newton*:Related Information:* 1 Newton = 1 kg m / s2 (kilogram meters per second squared)More force is needed to make a heavier thing accelerate more.
F = m a = (976) (2.5) = 2,440 newtons
Force = mass * acceleration and acceleration is in units of meters per second squared. I will assume you mean this. m/s2 Force = (1800 kg)(4 m/s2) = 7200 Newtons ----------------------
There is some confusion here. 500 newtons IS a force. You don't "give a force an acceleration". You can accelerate an object (which has a mass), but not a force.
Force is mass times acceleration. Assuming you mean an acceleration of 2 meters per second per second the force is 1 x 2 = 2N, south direction
[We changed the acceleration from 4 miles per second squared to 4 meters per second squared to make it more realistic. At 4 miles per second squared, it would be moving faster than it would have if it had been shot out of a cannon. A lot faster.] Force (f) = mass (m) times acceleration (a) f = 8 kg times 4 m / sec2 32 kilogram meters / sec2 As 1 kg m / sec2 = 1 Newton, 32 kg m / sec2 = 32 Newtons
acceleration...
Force = mass times acceleration F = 1 x 2 = 2 Newtons
F = ma(Force = Mass * Acceleration)F = (3) * (5)F = 15 N(15 Newtons)
Force = mass * acceleration Force = (3000 kg)*(2 m/s^2) = 6000 Newtons ---------------------- ( that is 6000 times the force needed to push in a doorbell, on average )
Force = Mass * Acceleration = 1 * 2 = 2 Newtons
