**Educational Problem Description:**Two blocks are connected by a light string that passes over a frictionless pulley as shown in the figure. The system is released from rest while \( m_2 \) is on the floor and \( m_1 \) is a distance \( h \) above the floor.**Diagram Explanation:**- The diagram shows a pulley system with two blocks, \( m_1 \) and \( m_2 \), connected by a string. - Block \( m_1 \) is suspended in the air, while block \( m_2 \) is on the floor. - The pulley is positioned above \( m_2 \).- The distance \( h \) is the initial vertical separation between \( m_1 \) and the floor.**Questions:** (a) Assuming \( m_1 > m_2 \), find an expression for the speed of \( m_1 \) just as it reaches the floor. (Use any variable or symbol stated above along with the following as necessary: \( g \).)\[ v = \_\_\_\_\_ \](b) Taking \( m_1 = 6.9 \, \text{kg}, \, m_2 = 3.9 \, \text{kg}, \) and \( h = 3.5 \, \text{m}, \) evaluate your answer to part (a).\[ v = \_\_\_\_\_ \, \text{m/s} \](c) Find the speed of each block when \( m_1 \) has fallen a distance of 1.2 m.\[ v = \_\_\_\_\_ \, \text{m/s} \]

PLEASE HELP ME Problem 2
The diagram below shows a mass that is oscillating on the end of a string at three different times t₁, t2, and t3 during a single cycle. At t, it is at maximum displacement in the negative direction. In the following questions we will disre- gard the centripetal acceleration of the bob due to its circular motion about the point O. a. Draw the velocity and acceleration vectors next to the pendulum bob at times t₁, t2, and t3 to show the direction and relative magnitude of those vector quantities at those positions. The vectors at time t₁ have already been drawn. Note: The centripetal acceleration that arises from the circular motion about O is neglected. Draw the forces acting on the bob at each of those instants. 11 a V At which instant t₁, t2, or t3 does the bob have the greatest velocity? What is the acceleration at that position? Explain. b. C.

Use the diagram to answer the questions A small block slides down a frictionless track whose shape is described by y = (x^2) /d for x<0 and by y = -(x^2)/d for x>0. The value of d is 2.29 m, and x and y are measured in meters as usual. Suppose the block starts from rest on the track, at x = -1.71 m. What will the block s speed be when it reaches x = 0? a. 5.01 m/s b. 3.54 m/s c. 1.06 m/s d. 8.02 m/s Same type of track as in the previous problem, this time with d = 3.60 m. The block starts at x = 0, and is given a push to the left with an initial speed of 2.23 m/s, so it starts sliding up the track to the left. At what value of x will the block reverse direction and start sliding back down? a. -0.25 m b. -0.96 m c. 0.96 m d. 0.25 m
