The speed of the dragster after travelling 325 m is still 45 m/s
Explanation:
In this problem, we are told that the dragster is travelling at constant rate, therefore its speed is constant and it is
v = 45 m/s
Therefore, its speed will remain constant during the entire motion: therefore, after having travelled for 325 m, its speed will still be 45 m/s.
We can also calculate the time taken for the dragster to cover the 325 m. In fact, the speed in a uniform motion is given by
[tex]v=\frac{d}{t}[/tex]
where:
v is the speed
d is the distance covered
t is the time elapsed
In this case, we have:
v = 45 m/s
d = 325 m
Solving for t, we find:
[tex]t=\frac{d}{v}=\frac{325}{45}=7.2 s[/tex]
