The scuba diver dove 50 feet and after every 2 minutes he rose 2 feet. That means, every minute, he rose 1 feet. After 12 minutes, the scuba driver must've rose 12 feet and -50+12 = -32, After 12 minutes he was 32(-32) feet deep in the water
constant acceleration- a
constant velocity- c
no velocity or acceleration- b
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.
