Two blocks are connected by a massless rope. The rope passes over an ideal (frictionless and massless) pulley such that one bloc

k with mass m1=14.25 kg is on a horizontal table and the other block with mass m2=7.5 kg hangs vertically. Both blocks experience gravity and the tension force, T. Find the magnitude of the tension in the rope, T, in newtons.

A rock falls from a tower that is 320 feet high. As it is​ falling, its height is given by the formula h equals 320 minus 16 t s
RSB [31]

Answer:

a. 4.5secs

Explanation:

From the question, the equation describing the height is given by

h(t)=320-16t^{2}\\

at the point when the rock hit the ground, the height,h will be zero.

Hence we can have

h(t)=320-16t^{2}\\\\at  h(t)=0\\0=320-16t^{2}\\hence \\320=16t^{2}\\t^{2}=\frac{320}{16}\\ t^{2}=20\\t=\sqrt{20}\\ t=4.47secs\\t=4.5sec\\

hence the rock will hit the ground in 4.5secs
