The function s = f(t)gives the position of a body moving on a coordinate line, withsin meters andtin seconds.s = 10t – t2, 0 ≤ t ≤ 10Find the body's speed and acceleration at the end of the time interval.

Answer:

Velocity will be -10 m/sec

Acceleration will be [tex]-2m/sec^2[/tex]

Step-by-step explanation:

We have given equation of distance [tex]s=10t-t^2[/tex]

Time is given as [tex]0\leq t\leq 10[/tex]

We have to find velocity and acceleration at end of time interval means at t = 10 sec

We know that velocity is rate of change of cdistnce

So velocity [tex]v=\frac{ds}{dt}=\frac{d(10t-t^2)}{dt}=10-2t[/tex]

At t = 0 sec

Velocity [tex]v=10-2\times 10=-10m/sec[/tex]

We know that acceleration is rate of change of velocity

So [tex]a=\frac{dv}{dt}=\frac{d(10-2t)}{dt}=-2m/sec^2[/tex]
