Arunning cheetah begins to slow down. for each meter the cheetah travels, its speed changes by −3.4−3.4 kilometers per hour. the cheetah travels a total of 21.5 meters. what is the total change in the cheetah's speed during this time?

a. 73.1

b. 71.9

c. 18.1

d. -18.1

e. -71.9

f. -73.1

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.

62.5 paisa

step-by-step explanation:

4000*70 = 280000

280000-(2000*90) = 100000

4000-2400 = 1600

100000/1600 = 62.5
