Question 1 1.1 If the velocity distribution of a fluid flowing over a 1m² flat plate is given by u=l+ y + y, find the m. Assume dynamic viscosity to be y=6x10*(Ns/m”). force acting on a plate at y = [5 marks] 1.2 A 2D velocity field in an incompressible flow was measured by PIV method and determined to follow the following functions u= 2x’ +2y and v=x - 4y. Check whether your measurements are correct at a...
A
block of mass 3 kg goes down at a velocity 5.45 over an inclinated
plane with an angle of 40º when it is at a distance of 1m of a
spring with a constant of 366N/m. the coefficient of kinetic
friction betweeen the block and the surface is 0.2. calculate the
velocity of the block when it touches the spring for the first
time.

A frog jumps from a rock through a distance of 1m (horizontally) to the center of a lily pad. The change in height from the rock to the lily pad is Ay = 0.3 m downward. It jumps at an angle 0o 37 (upward) relative to the horizontal. The figure shows a side view also. Ignore air resistance. With what initial speed vo did the frog jump if it landed in the center of the lily pad? Give your answer...
A
block of mass 3 kg goes down at a velocity 3.73 over an inclinated
plane with an angle of 40º when it is at a distance of 1m of a
spring with a constant of 251N/m. the coefficient of kinetic
friction betweeen the block and all of the surface is 0.2.
calculate the maximum compression of the spring .
2. (1 point) Two infinitely long vertical wires are separated by a distance of 1m. One wire carries an upwards going current of 2 A, while the other carries the same current in the opposite direction. What is the magnitude of the magnetic field half way between the two wires? 2h, I
Relative Velocity vs. Time Graph Ranking Task Rank car #1's speed relative to the ground at the lettered times (A through E). Constants Rank from largest to smalest. To rank Items as equivalent, overlap them. Two cars travel on the parallel lanes of a two-lane road. The cars are at the same location at time t 0s, and move in such a way as to produce the velocity (relative to the ground) vs. time graph shown in (Figure 1). On...
en Consider the following velocity function. Complete the sentence: The same distance could have been traveled over the given time period at a constant velocity of 1/2 v(t) = 4t(9-12) for Osts3 The same distance could have been traveled over the given time period at a constant velocity of |
