![5. Moving Vehicle and Falling rain 0 0 0 rain frictionless A vehicle ofdry mass mo , with no propulsion, is moving without friction on horizontal ground as shown in the figure above. Rain is falling vertically. While the rain is falling, for each time interval Δt, an amount of rain Δmr-łAt hits the vehicle, sticks to it and then moves along with zero relative velocity with respect to the vehicle. The vehicle is observed to be slowing down. In a reference system fixed to the ground, at time t 0, the cart is initially moving with speed vo a) At time t, the vehicle is traveling with speed v(t). For the time interval t, t +At], while the rain is falling, determine a differential relation for the change in speed of the vehicle Δυ. Write your answer using some or all of the following: t. At, m0 and b (b) Integrate your result from part a) to find the speed v(t) of the cart at time t. Write your answer using some or all of the following: vo, b, mo andt](http://img.homeworklib.com/questions/94f4f0c0-6fcf-11ea-82cb-5926074b1e5f.png?x-oss-process=image/resize,w_560)

(7%) Problem 14: A spherical rain drop of radius R and mass M falls vertically through a cloud layer. The drop enters the cloud layer at a height H from the ground and exits the cloud at a height h. While inside the cloud the drop accumulates water molecules so that its mass and size grow with time. The mass of the rain drop at time t when inside the cloud is given as follows: m(t) = M + at...

A mass is connected to a spring and moving on a frictionless
surface as in the picture below:
Assume that the spring is massless and
has a spring constant value of 300[N/m]. Assume that the mass is 3
[kg]. Assume that the spring starts at equilibrium (y=0) while
moving to the right at speed v. Assume that it reaches a maximum
displacement of 5 cm.
Write an expression for the velocity
of the mass versus time. The only variables...

5) Acceleration is to velocity as velocity is to position . aaux"# r where vr įs the instantaneous velocity. So the average acceleration is about how rapidly the instantaneous velocity is changing, and the sign tells about the direction of the change. At For the pendulum, you made estimates of the instantaneous velocity for ←2.05[s] and t= 2.5%]. Also, the average speed and average velocity estimates that you made at other times may be reasonable...
