(B): Derive the relation between force and acceleration .(C): Define the SI unit of force. |
| Answer» According to the Newton\'s first law of motion the force is directly related to the change in momentum of a body, soF = dp/dtnow momentum is given a. p = mvwhere m is the mass and v is the velocityso,F = d(mv)/dt = m(dv/dt)or we getF = maDefinition of one unit forceThe movementum is defined as the product of its mass and velocity.movementum = mass x velocityor p = m x vwhere p = movementumm = mass (kg)v = velocity (m/s)SI unit is kg-m/sThe total momentum of the gun and bullet before firing is zero as both of them are at rest.\xa0 | |
