Answer 1

Answer:

See explanation.

Explanation:

(a) a = (v-u)/t = (25-0)/3 = 8.333333333 (or 8.3 recurring) $m/s^{2}$.

(b) a = (v-u)/t = (17.5-25)/1 = -7.5 $m/s^{2}$.

(c) distance = area covered under graph = triangle ABE = 1/2bh = 1/2 x 3 x 25 = 37.5 m.

(d) distance = area covered under graph = trapezium BCFE = 1/2(a+b)h = 1/2 x (25+17.5) x 1 = 21.25 m.

Good luck, student!
