ho so easy lol ummm yawn hmmm a= delta v/ delta t delta is change in stuff so v final - v initial is 20 in 7.5 so dividing it would be 2.66666666 but it would be negative since its negatively acceleration so -2.6666666 so and plug it in a=delta v/ delta t so its -2.66666666 = vf - 35/ 3 so hmm -7.999999999=vf-35 and approximately 27m/s
