the tires of a certain car begin to lose their grip on the pavement at acceleration of 5 m/s to the power of 2 if the car has this acceleration , how many seconds does it required reaching a speed of 25 m/s starting from 10 m/s?.
Please help me
a = 5 m/s^2
v = Vi + a t
25 = 10 + 5 t
To find the time required for the car to reach a speed of 25 m/s from 10 m/s, we can use the equation:
v = u + at,
where:
v - final velocity = 25 m/s,
u - initial velocity = 10 m/s,
a - acceleration = 5 m/s^2,
t - time.
Rearranging the equation, we get:
t = (v - u) / a.
Plugging in the values, we have:
t = (25 - 10) / 5.
Simplifying:
t = 15 / 5.
Therefore, the time required is:
t = 3 seconds.
So, it would take 3 seconds for the car to reach a speed of 25 m/s from 10 m/s with an acceleration of 5 m/s^2.
