Question

12 points The position as in meters of a body as a function of the time tin seconds is given by a = 1x4. What is the instanta

Answer 1

Answer #1

We know that instantaneous velocity is

V_inst=dx/dt

Given x =(1/4)t⁴

So

V_inst=(1/4)d (t⁴)/dt

V_inst=(1/4)(4t³) = t³

^V_inst=t³

Given that t=2.0 s

V_inst=(2)³ =8 sec

V_inst= 8sec

Ans is V_inst= 8 sec
