How Much force is needed to accelerate 1,300 kg car at a rate of 1.5 m/s squared?

Assuming there is no force of friction...

F = ma

F = (1300kg)(1.5m/s^2)

F = 1950N

it somewhat is a good question! I dont recognize, yet consistent with danger it fairly is by using certainty the rigidity is fairly too small for us to be wakeful. for an prolonged time the only way they have even detected the enlargement is by utilising utilising the crimson shift of the spectra of distant stars. in spite of the easy certainty that, are the instruments indoors the universe increasing? As I comprehend it, the instruments are all moving removed from one yet yet another, ensuing in a sort of the universe containing the instruments, inspite of the incontrovertible fact that the instruments themselves are no greater increasing; they are fairly moving removed from one yet yet another at a continuing velocity. For the instruments (which contain our Earth) to alter velocity will require an outdoors rigidity, which we would locate. As for rotational dynamics, technically acceleration is a metamorphosis in velocity. velocity includes no longer in basic terms a velocity yet a course too. If a course adjustments inspite of the incontrovertible fact that the appropriate value is continuing (which contain in a rotation), that's considered acceleration. yet for that to ensue, a rigidity could be utilized to reason the substitute in velocity. in case you connect a ball to a string and spin around, you're pulling on the ball inflicting the path to alter, suffering with the ball from moving in a interior the well known line; you're consistently using hysteria interior the path of your self. If the ball breaks loose, the rigidity could be long long gone and the ball will shoot outward in a interior the well known line, no longer greater desirable rotation. a matching is truthfully with gravity preserving us interior the worldwide by using certainty the Earth spins and we stay on it, pulled inward interior the path of its center without taking photographs off in a tangential action (ouch!). you're stable that too many human beings don't understand that 65mph is a continuing velocity, and for this reason no acceleration, and you're stable that we are going to experience acceleration. as quickly as you're indoors a automobile and the automobile hastens, you develop up with it, and you experience it. If a airplane flies at consistent velocity (and no turbulance) it fairly is not achieveable to locate the severe velocity you're travelling by using certainty there is not any longer any acceleration. Einstein taught us all this and that's undertaking-loose physics.
