Answer:
5m/s/s
Explanation:
10N bc you subtract 10N from 20N and you get 10
a=f/m
F=10N
m=2kg
10/2=5
Answer:
is the rate of change of its position of an object with respect to a frame of reference, and is a function of time. Velocity is equivalent to a measure of an object's speed and direction of motion.

Answer:
acceleration of the particle as a function of time is given as
![a(t)=-\frac{ks}{t}](https://tex.z-dn.net/?f=a%28t%29%3D-%5Cfrac%7Bks%7D%7Bt%7D)
and position of the particle as a function of time is given as
![x(t)=ut+\frac{at^2}{2} \\x(t)=V_{0}t-\frac{\frac{ks(t)}{t}t^2}{2}](https://tex.z-dn.net/?f=x%28t%29%3Dut%2B%5Cfrac%7Bat%5E2%7D%7B2%7D%20%5C%5Cx%28t%29%3DV_%7B0%7Dt-%5Cfrac%7B%5Cfrac%7Bks%28t%29%7D%7Bt%7Dt%5E2%7D%7B2%7D)
![x(t)=V_{0}t-\frac{kst}{2}](https://tex.z-dn.net/?f=x%28t%29%3DV_%7B0%7Dt-%5Cfrac%7Bkst%7D%7B2%7D)
Explanation:
we have given,
![v=v_{o}− ks](https://tex.z-dn.net/?f=v%3Dv_%7Bo%7D%E2%88%92%20ks)
at t=0, s=0
therefore initial velocity,u
u=v=![V_{o}](https://tex.z-dn.net/?f=V_%7Bo%7D)
v=u+at.........(1)
we know from first equation of motion
let acceleration at time t be a(t), and position be x(t)
put value of v,u and a in equation 1
we got,
![V_{o}-ks=V_{o}+a(t)t](https://tex.z-dn.net/?f=V_%7Bo%7D-ks%3DV_%7Bo%7D%2Ba%28t%29t)
Therefore,acceleration of the particle as a function of time is given as
![a(t)=-\frac{ks}{t}](https://tex.z-dn.net/?f=a%28t%29%3D-%5Cfrac%7Bks%7D%7Bt%7D)
and position of the particle as a function of time is given as
![x(t)=ut+\frac{at^2}{2} \\x(t)=V_{0}t-\frac{\frac{ks}{t}t^2}{2}](https://tex.z-dn.net/?f=x%28t%29%3Dut%2B%5Cfrac%7Bat%5E2%7D%7B2%7D%20%5C%5Cx%28t%29%3DV_%7B0%7Dt-%5Cfrac%7B%5Cfrac%7Bks%7D%7Bt%7Dt%5E2%7D%7B2%7D)
![x(t)=V_{0}t-\frac{kst}{2}](https://tex.z-dn.net/?f=x%28t%29%3DV_%7B0%7Dt-%5Cfrac%7Bkst%7D%7B2%7D)
