Calculate the time taken for a car to cover a distance of 125m .if the initial speed is 5m/s and has a constant acceleration of 1.5m/s?

First, we need to find the final speed of the car using the formula:

v^2 = u^2 + 2as

Where:
v = final speed
u = initial speed = 5 m/s
a = acceleration = 1.5 m/s^2
s = distance = 125 m

Plugging in the values:

v^2 = (5)^2 + 2(1.5)(125)
v^2 = 25 + 375
v^2 = 400
v = √400
v = 20 m/s

Now, we can calculate the time taken using the formula:

t = (v - u) / a

Plugging in the values:

t = (20 - 5) / 1.5
t = 15 / 1.5
t = 10 seconds

Therefore, the time taken for the car to cover a distance of 125m is 10 seconds.
