Answer:
Find attached of the diagram that complete the question.
Velocity = 1.5 sec²θ m/s
Acceleration = 9 sec²θtanθ m/s²
Explanation:
Calculating the velocity:
V = dx/dt
x = 0.5tanθ
θ = 3t
ö = 3
V = d(0.5tanθ)/dt
= 0.5*sec²θ*ö
= 3*0.5sec²θ
= 1.5 sec²θ m/s
Calculating the acceleration, we have;
a = dv/dt
= d(1.5sec²θ)/dt
= 1.5*2sec²θtanθ*ö
= 1.5*2sec²θtanθ*3
= 9sec²θtanθ m/s²
Answer:
The mechanical advantage is 3 to 1
Explanation:
A frictionless pulley with three support ropes carries equal tension on each of the ropes thus;
Tension in each pulley rope = T
Total tension in the 3 ropes = 3 × T = 3·T
Direction of the tension forces on each rope = Unidirectional
Total force provided by the 3 ropes = 3·T
Therefore, a force, T, applied at the end of the rope will result in a lifting force of 3·T
Hence, the mechanical advantage = 3·T to T which is presented as follows;
The mechanical advantage = 3 to 1.
