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
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.

F = m a = (976) (2.5) = 2,440 newtons
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 = 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.
acceleration...
[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
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
Force = mass times acceleration F = 1 x 2 = 2 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
If it is a solid cube, then it 125 meters squared. If it just the floor, its 25.
10,000 square meters is equivalent to 10,000 square meters. No conversion is needed since they are the same unit of measurement.
