Yohanna is conditioning all summer to be fit for the next soccer season at his high school. he incorporated walking planks into his daily workout regime. each day, he will complete 4 more walking planks than the day before. if he starts with 5 walking planks on the first day, how many walking planks will he do on the twelfth day?

constant acceleration- a

constant velocity- c

no velocity or acceleration- b

explanation:

for body moving with a constant acceleration, the rate of change of displacement changes over time. this is proven by the increasing gradient of the curve (a) against time.

a body that is moving at constant velocity covers equal distances over equal periods of time, thus the straight line with a constant gradient c.

a stationary body   covers no displacement as time elapses. thus the flat line with   zero gradient.
