Webforce= change in momentum/time taken. what is the force causing the change equal to? the rate of change of momentum. so a larger force means? a faster change of momentum. if someone's momentum change's very quickly, what will the force be like? very large. why are cars designed to slow people down over a longer time when they … WebF = ma , or force = mass x acceleration. Recall that acceleration is rate of change of velocity, so we can rewrite the Second Law: force = mass x rate of change of velocity. Now, the momentum is mv, mass x velocity. This means for an object having constant mass (which is almost always the case, of course!)

WebThe rope stretches when the jumper jumps off the spot. The elasticity of the rope helps in increasing the time with which the momentum changes. This reduces the effect of impact force on the jumper and reduces the … WebIn the first 4 seconds, the acceleration is constant (the force is constant) and can be found by using F=m*a which in this case is 3=2.9*a so a = 1 m/s^2 For seconds 3 to 7, we can find the acceleration by finding the mean force, which is 3/2= 1.5 N and then, 1.5=2.9*a so … Momentum of A in the x direction is going to equal square root of 3 times 10.
