Plz. help ) An auto accelerates forward from 7.0 m/s at a uniform 0.71 m/s?. It travels a distance of 1033 m while
accelerating

(a) How fast is the auto moving just as it is traveled
the 1033 m?

(b) How many seconds did it take to travel the 1033 m?

The auto is moving at 38.9 m/s

The auto took 45 seconds to travel the 1033 m

Explanation:

Constant Accelerated Motion

it's a type of motion in which the velocity of an object changes uniformly in time.

The relationship between initial and final speeds is calculated by the equation:

Where a is the constant acceleration, vo the initial speed, vf the final speed, and t the time.

Another useful equation allows us to calculate the distance x traveled by the object:

(a)

Solving [1] for t and substituting into [2] we find the equation:

This last equation will be used to solve the first part of the problem which gives the initial speed of vo=7 m/s, the uniform acceleration as a=0.71 m/s^2 and the distance traveled as x=1033 m, thus substituting:

Thus:

The auto is moving at 38.9 m/s

(b)

To calculate the time, we solve [1] for t:

The auto took 45 seconds to travel the 1033 m

i don’t know what the answer is i wish i
