The expansion rate of the Universe is usually given as something like 70 km s−1 Mpc−1. If you convert this quantity to SI base units of kg, m, s, what is this number and in what units? What do you think this means for the age of the Universe? Give an estimate for the age of the Universe, in s and in billions of years.

2. Complete the following for the impermeable dam shown below: a. Identify a datum, indicate the first and last equipotential lines, and indicate the first and last flow lines b. Draw the flow net and determine the seepage under the dam. Calculate the pore water pressure (u) at points A, B, and C (in units of kPa). d. c. Estimate the uplift force (Fu) under the concrete dam (in units of kN/m of length) Note: an additional figure is included...
2 m datum datumu k= 15 N/m The 1.0 kg collar is given a downward velocity of vg= 8.0 m/s when it is at A. The spring has an unstretched length of 1 m. The collar travels a distance s= 1.5 m to point C. What is the elastic potential energy of the system when the collar is at A?

A car drives straight off of a horizontal cliff with a speed of 54.9 m/s. If it is in the air for 4.01 s, how far from the base of the cliff does the car land? And what is the height of the cliff? X= | Number | | Units Y= | Number | | Units
A 2.70 kg box is moving to the right with speed 8.50 m/s on a horizontal, frictionless surface. At t = 0 a horizontal force is applied to the box. The force is directed to the left and has magnitude F(t)=( 6.00 N/s2 )t ^2 What distance does the box move from its position at t=0 before its speed is reduced to zero? Express your answer with the appropriate units. If the force continues to be applied, what is the...
