For the kinematic way i get v^2=196 and for energy way as sal stated we get v^2= 200 now i realise the difference is not huge with V=14ms/s for the kinematic way and V=14.14m/s for the energy way, but why does the difference exist if both methods can determine the same results? •

The force of kinetic friction acts to oppose the motion of the object, so if you push something forward, friction pushes it backwards. The kinetic fiction force only applies to an object ... getnthrecord filemakerWebMar 16, 2024 · The kinetic energy equation is as follows: KE = 0.5 × m × v², where: m – Mass; and. v – Velocity. With the kinetic energy formula, you can estimate how much energy is needed to move an object. The same … get nuget package path in c#WebIf we take "g" to mean 10 m/s^2, we end up with 1 J=1 kgm^2/s^2, but if we take g=10 N/kg, the kg cancel out and we get Nm. • 1 comment ( 3 votes) schnack.morten 12 years ago Definition of Newton: N = (kg*m)/ (s^2). Your question: g = 10 m/ (s^2). By the definition this is equal to g = 10 N/kg. They are the same! Also: 1 J = 1 kg*m^2/s^2 = 1 N*m. get nth node from end of linked listWebKinetic Energy Practice Problems 1. What is the Kinetic Energy of a 150 kg object that is moving with a speed of 15 m/s? KE = ½ mv2 KE = ? m = 150kg v = 15m/s KE = ½ (150kg) … christmas term datesWebKE = 0.5 • m • v2 where m = mass of object v = speed of object This equation reveals that the kinetic energy of an object is directly proportional to the square of its speed. That means that for a twofold increase in speed, the kinetic energy will increase by a factor of four. get nth row pandas
