An automobile with an initial speed of 4.56m/s accelerates uniformly at the rate of 2.4m/s2.
Find the final speed of the car after 4.4 s.
Answer in units of m/s.

To find the final speed of the car after 4.4 seconds, we can use the formula for uniform acceleration:
Final Speed (v) = Initial Speed (u) + Acceleration (a) × Time (t)
Given:
Initial Speed (u) = 4.56 m/s
Acceleration (a) = 2.4 m/s²
Time (t) = 4.4 s
Substituting these values into the formula, we can calculate the final speed:
v = u + a × t
v = 4.56 m/s + 2.4 m/s² × 4.4 s
First, multiply the acceleration (a) by the time (t):
v = 4.56 m/s + 10.56 m/s
Then, add the two values together:
v = 15.12 m/s
Therefore, the final speed of the car after 4.4 seconds is 15.12 m/s.
