(III) You are lying on a beach, your eyes 20 cm above the sand. Just as the Sun sets, fully disappearing over the horizon, you immediately jump up, your eyes now 150 cm above the sand, and you can again just see the top of the Sun. If you count the number of seconds(= t) until the Sun fully disappears again, you can estimate the Earth’s radius. But for this Problem, use the known radius of the Earth to calculate the time t.
You and a friend are raising a beam, but your friend's rope is too short so you lift him off the ground. At the current time, everything is static. The tension in your cord is 1045.6 N, the mass of the beam is 15 kg, and the mass of your friend is 85 kg. The length of the beam is 4.9 m, d = 3.9 m, theta = 43.5 degrees, phi = 62.5 degrees. If you choose the base of the beam as the origin, and the positive torque direction as counter-clockwise, what is the torque from your cord on the friend+beam system?
Two objects moving along x-axis are starting at the same time. Their positions are measured in centimeters at time t in seconds. If the equation of motion of objects 1 and 2 are and respectively, determine the distance between the objects at the instant when they have the same velocity. 2 cm 4 cm 3 cm 1 cm
A ball is thrown vertically upwards with a velocity of 48 ft/s from the top of a building 35 ft high. How high from the top of the building will the ball go? Consider two objects moving along x-axis are starting at the same time. Their positions are measured in centimeters at time t in seconds. If the equation of motion of objects 1 and 2 are s1 = 2t2 -3t and s2 = 3t-t2 respectively, determine the distance between the objects at the instant when they have the same velocity. If , x = Arctant3 , y = √1+t6 find the value of a if 2ay'' / y' when t =√2
(6 )Suppose you're standing on the ground and throw a frisbee. You want the expression for the acceleration of a point on the edge of a frisbee (flying, rotating disk) in flight relative to yourself. If you know the acceleration of the frisbee's center of mass relative to yourself and the position of your point of interest on the frisbee's edge relative to the frisbee's mass center at a particular instant, what other information would you need? nothing - you have all the information you need the frisbee's angular acceleration the frisbee's angular velocity the frisbee's angular velocity and angular acceleration
A boat is aimed at the opposite shore of a 418.51 m wide river and rowed at a speed of 7.89 m/s relative to the water. The current in the river is at a right angle to the velocity of the boat relative to the water. The current in the river is at 2.27 m/s. What is the speed of the boat relative to an observer on the shore?
Make a graph of x versus t for the ball. Because you havedata only at certain instants of time, your graph should consist of dots that are not connected together.
The complete slide- back and forth motion of a single reciprocating compressor piston completes in a 2-sec period. The volume displacement of the piston though the piston cylinder is 8,902.63 in3. The stiffness of crank is said to be equal to 65.5N/m and the mass of the said piston is at 10kgs. Obtain the following 1. Plot the graph of the following relationship: A) Position vs Time graph B) Velocity vs Time C) Acceleration vs Time
You walk along the beach towards a dock while your friend rows a boat towards the same dock on a flat lake. Your friend's boat approaches the dock on a straight course, but also rotates about its center-of-mass since your friend is not pulling evenly on the oars. If you knew your own velocity (vwalker), the magnitude of boat's angular velocity (thetaboat), and radius vector from yourself to your friend in the boat (rfriend) at any given time, you could use the following equation to calculate the your friend's velocity: vfriend = vwalker + (thetaboat)k x rfriend where k is a unit vector in the vertical direction. True False
A sliding block C moves along a horizontal line Q2C. A rotation arm Q2B is 4 ft 3 in long and rotates around a center Q2. The connecting rod BC is 8 ft long. This rod is extended to D, making BCD 11 ft 9 in long. Make a drawing of this linkage and trace the path of D while the arm makes 1complete revolution CCW. Locate points for each 15 deg movement of the arm Q2B, beginning with Q2B coinciding with Q2C. Scale: 1 in = 1 ft

1. A surge is moving at 9 f t/s into a basin of depth 1.4 f t where the speed is zero. Find the water depth behind the surge and the drift velocity behind the surge (that is, the velocity downstream of the surge in a stationary frame of reference). 2. A river of depth 2 m flows downstream at 1 m/s. A surge of depth H moves up the river at 5 m/s relative to a stationary observer on the bank of the river. Find H.
