The answer would be:

Houlette de berger.

After 4 seconds the velocity **function** attains a=8.75m/s².

Given-

Velocity= 35m/s

time=4sec

To find out **acceleration**, we can understand the following-

Acceleration means rate of change of **velocity**.

In this question the velocity depreciates to zero i.e. the slope of the graph falls off with **negative slope**.

This value has negative impact on force as the resultant force is outcome of application of **brakes** where V=0 as time progresses.

Mathematically,

v- means velocity .

calculations-

a=35/4

a=8.75m/s²

Answer: 1.32 m/s^2

Explanation:

Centripetal acceleration is given by the formula

a = ( v^2 ) / r

where a is centripetal acceleration, v is velocity and r is radius.

We know that,

v = 5 m/s

r = 19m

Now,

a = ( v^2 ) / r

a = ( 5^2 ) / 19

a = 25 / 19

a = 1.32 m/s^2
