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.
7.5 watts
Work done (joules) and time taken (seconds) is the information needed to calculate power in watts (joules/second).
To determine how many pencils will make one kilometer, we first need to establish the average length of a pencil. A standard pencil is typically around 7 inches long (or 0.1778 meters). To convert one kilometer into meters, we multiply 1,000 by 1,000, resulting in 1,000,000 meters. Dividing 1,000,000 meters by 0.1778 meters per pencil gives us approximately 5,621,302 pencils needed to make one kilometer.
The answer depends on the mass of the piano and the height of the floor.
Power = (energy) / (time) =(200 newtons x 4 meters) / (4 seconds) =200 newton-meters per second = 200 watts

F = (m) x (A) = (1) x (12) = 12 newtons
A newton is the unit of force in the International System of Units (SI). It is defined as the amount of force needed to accelerate a mass of one kilogram by one meter per second squared.
Force = mass times acceleration F = 1 x 2 = 2 Newtons
The force needed can be calculated using Newton's second law: force = mass x acceleration. So, force = 68 kg x 5 m/s² = 340 N. Therefore, a force of 340 Newtons is required to accelerate a 68 kg skier at 5 m/s².
To calculate the force needed to accelerate a 15-kilogram bicycle at a rate of 10 meters per second squared, you can use Newton's second law of motion, which states that force equals mass times acceleration (F = m × a). Here, the mass (m) is 15 kg and the acceleration (a) is 10 m/s². Therefore, the force required is F = 15 kg × 10 m/s² = 150 Newtons.
Force = Mass * Acceleration = 1 * 2 = 2 Newtons
1kg of mass = 9.81 newtons 1kg = 9.81 newtons 1 newton = 0.101971621 kilogram-force 1 kilogram-force = 9.80665 newton Newton is not a unit of mass like the kilogram, it is a measure of force. A Newton is the amount of force that it takes to accelerate a mass at a rate of 1ms-2 The Earths gravity typically pulls 1kg. with a force of about 9.81N (N=Newton) but it varies a little depending where you are on Earth. So on Earth 0.102 Kg or 102 grams is one whole Newton
A Newton is equal to the SI unit of force, which is equivalent to around 0.22 pounds of force or the force needed to accelerate a 1 kilogram mass at a rate of 1 meter per second squared.
The unit of force abbreviated by N is Newton. It is named after Sir Isaac Newton and is used to quantify the amount of force needed to accelerate a mass of one kilogram at a rate of one meter per second squared.
