The speed of a car, measured in miles per hour, was determined 10 times at random. The results are 22, 43, 35, 32, 41, 28, 29, 30, 37, and 43 miles per hour. Construct a 95% confidence interval for the mean speed of this vehicle.

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.
