A 6.00-kg crate is suspended from the end of a short vertical rope of negligible mass. An upward force F(t) is applied to the en

timofeeve [1]

Answer:

The magnitude of F when t=4 s=146.64 N

Explanation:

We are given that

Mass of crate,m=6.00 kg

Height of crate above its initial position is given by

$y(t)=(2.80 m/s)t+(0.610 m/s^3)t^3$

We have to find the magnitude of F when t=4.00 s

Differentiate w.r.t t

$\frac{dy}{dt]=2.8+3(0.61)t^2$

$\frac{d^2y}{dt^2}=6(0.61)t$

$a(t)=\frac{d^2y}{dt^2}=6(0.61)t m/s$

$a(4)=6(0.61)(4)=14.64 m/s^2$

Now, magnitude of force

$F=m(a+g)=6(14.64+9.8)=146.64N$

Hence, the magnitude of F when t=4 s=146.64 N
