An automobile with an initial speed of 4.30m/s accelerates uniformly at the rate of 3.00 m/s2 find the final speed and the displacement after 5.00s

1) Final speed

The final speed of the car after t=5.00 s can be found by using the following equation:

where u is the initial velocity, a is the acceleration and t the time. In this problem, u=4.30 m/s, a=3.00 m/s^2 and t=5.00 s; substituting these data into the equation, we find

2) Displacement

The displacement of the car can be calculated by using the following equation:

Substituting the data of the previous part of the problem, we find

260 miles per hour

explanation:

answer: the answer is a
