You've already chosen the best response. It's a vector because acceleration has both a direction and a magnitude. An example would be a car stopping at a rate of 10 m/s. In this example the direction of acceleration is opposite the direction of velocity (towards the trunk) and the magnitude is 10 m/s.Show full answer.ou've already chosen the best response.

Even a goodfitting saddle can slide forward on a mulewhen conditions are right. In this case theaddition of a properly adjusted crupper orbritchen is needed to keep the saddle whereit belongs. At the same time, a mule with theright confirmation can cause a saddle toslide too far back and cause dry spots.
Dark spots are the result of the overproduction of melanin, or skin pigment. It's not fully understood why they develop, but aging and UV light exposure - even artificial UV light, like tanning beds - are major causes.
