A landscape architect is planning an artificial waterfall in a city park. Water flowing at 1.70 m/s will leave the end of a horizontal channel at the top of a vertical wall h = 2.35 m high, and from there it will fall into a pool (Fig. P4.22). (a) Will the space behind the waterfall be wide enough for a pedestrian walkway? (b) To sell her plan to the city council, the architect wants to build a model to standard scale, which is one-twelfth actual size. How fast should the water flow in the channel in the model?
A man drops a rock into a well. (a) The man hears the sound of the splash 2.40 s after he releases the rock from rest. The speed of sound in air (at the ambient temperature) is 336 m/s. How far below the top of the well is the surface of the water? (b) What If? If the travel time for the sound is ignored, what percentage error is introduced when the depth of the well is calculated?
A bungee jumper falls for 1.3 s before the bungee cord begins to stretch. Until the jumper has bounced back up to this height , the elastic cord causes the jumper to have an average acceleration upward of 4 m/ a) How fast is the jumper going when the bungee cords begins to stretch?

6. Consider a spring-mass system given by mu" + yu' + ku=0. a. Suppose y2>4mk and the initial conditions are u(0) = 5, u'(0) = a HUGE negative number. How many time(s) will the mass pass through the equilibrium position? JUST GIVE ME A NUMBER AS YOUR ANSWER. Infinity is considered a number. b. Same as above with y² = 4mk and u(0) = 2, u'(0) = a HUGE positive number. Infinity is considered a number. C. Suppose <4mk and the initial conditions are u(0) = -.0001, u'(0) = 0. How many time(s) will the mass pass through the equilibrium position? JUST GIVE ME A NUMBER AS YOUR ANSWER. Infinity is considered a number. d If y = 2 what is the limit of u(t) as too? JUST GIVE ME A NUMBER AS YOUR ANSWER. Infinity is considered a number.
6. A block of mass 40 g is attached with a spring. If the normal length of spring (without attaching block) was 10 cm and after attaching the block, new length of spring is 12 cm. Calculate the spring constant as per the Hook's law.
5.A student finds a spring that is labeled k=45 N/m. She hangs it vertically and attaches a 500 g mass to it. If the spring is originally 30 cm long, how long will it stretch when the mass is attached?
A.20 m long spring is attached to the wall. When pulled horizontally with a force of 100 N, the spring stretches to a length of .30 m. -.20 m .30 m 100 N a) Calculate the value of the spring constant.
You are sitting on a deck of your house surrounded by oak trees. You hear the sound of an acorn hitting the deck. You wonder if an acorn will do much damage if instead of the deck it hits your head. Let the mass of the acom be 3.1g Suppose it drops from a height of 13 m (relative to your head). Assume that the acorn sinks in 0.50 cm of your head skin before coming to a stop. Determine the magnitude of the force that the acorn would exert on the head.
.A body that weighs W Newtons falls from rest from a height of 600mm and strikes a spring whose scale is 7.00 N/mm. If the maximum compression of the spring is 150 mm, what is the value of W? Disregard the mass of the spring. (Ans. W=105 N) w 600mm 150mm
