A 5.00 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
gayaneshka [121]

Answer: 75.05N

Explanation:

According to newton's second law,

Force = mass×acceleration

Given mass = 5.0kg

Acceleration = change in velocity/time

Velocity = change in displacement/position/time i.e dy/dt

Given position of the particle as y(t)=(2.80 m/s)t +(0.61 m/s)t³

dy/dt = 2.80 + 3(0.61)t²

V = dy/dt = 2.80 + 1.83t²

Acceleration (a) = dv/dt = 2(1.83)t

dv/dt = 3.66t

To get the force when t =4.10second

dv/dt @ t = 4.10s will be 3.66(4.10)

acceleration = 3.66×4.10 = 15.01m/s²

Magnitude of the force F = ma

F = 5.0kg × 15.01m/s²

F = 75.05N
