Answer:
(a). The velocity is 0.099 m/s.
(b). The position is 19.75 m.
Explanation:
Given that,
The deceleration is

We need to calculate the velocity at t = 25 s
The acceleration is the first derivative of velocity of the particle.



On integrating


....(I)
At t = 0, v = 10 m/s


Put the value of C in equation (I)



The velocity is 0.099 m/s.
(b). We need to calculate the position at t = 25 sec
The velocity is the first derivative of position of the particle.

On integrating


At t = 0, s = 15 m



Put the value in the equation


The position is 19.75 m.
Hence, (a). The velocity is 0.099 m/s.
(b). The position is 19.75 m.
Force = mass x acceleration
113N = 25.2a
a = 4.48 m/s^2
Vf = Vi + at
Vf = 2.33 + 4.48(2) = 11.3 m/s
