Dynamics of Rigid Bodies
1.) From the top of a tower an object is thrown vertically downward with a velocity of 20 m/s. What is the velocity of the object after it has fallen 60 metres?
2.) A diver jumps from a height of 3.0 metres above the height of the water and touches the surface 1.0 s later. What was his velocity when he hit the water?
3.) A motorcyclist, travelling at a speed of 30 m/s, sees an obstacle 100 metres in front of him and puts on the brakes. He hits it 5.0 seconds later. If the motorcycle slows down uniformly, how fast was it going at the instant of the collision?

- An exuberant 30 lb beagle awaiting dinner jumps to a height of 2.5 feet once every 4 seconds. The beagle continues this for 5 minutes. If the beagle is 20% efficient at converting kibble calories into motion, how many grams of kibble will it need to fuel this activity? Dry canine fare, for the most part, contains roughly 97 Calories for each 1 ounce. From the waste heat, how much (degC) will the beagle's temperature increase (all else equal and no heat loss to the surroundings)? Remember a food Calorie is actually a kcal.arrow_forwardfluid mechanicsarrow_forwardA 3-meter-long 25 kg beam is supported by two cables as shown below. You can treat the beam as a slender rod. Assume we want the left end of the beam at A to remain as a constant height while the right end of the beam at B to accelerate upwards at a rate of 1 m/s². a) What is the rate of acceleration of the center of the beam and the rate of angular acceleration for the beam? b) What will T₁ and T₂ need to be to achieve these accelerations?

- Suppose a body of mass (m) falls from a height (h) under gravity. It lands on a frictionless spring with spring constant (k). Which of the following expressions represents the spring compression (length change) at the time the falling body has come to rest?

Nota Bene: Consider only what happens to the star during its collapse, not what may happen to it later. A Its rotation will slow down. B It will rotate at the same speed. C Its rotation will speed up.arrow_forward
- 3. A pulley is driven by a flat belt running at a speed of 600 m/min. The coefficient of friction between the pulley and the belt is 0.3 and the angle of lap is 160°. If the maximum tension in the belt is 700 N ; find the power transmitted by a belt. [Ans. 3.983 kW]arrow_forwardA 3.1 kg object is initially at rest and is experiencing a net force of magnitude 4.7e^-t/2 N. As time approaches infinity, notice that the net force decays toward 0 N, which tells us that the acceleration is also dropping to 0 m/s^2 (and so the velocity is leveling off to a terminal speed). What is the terminal speed? (Ans.= 3.0 m/s)arrow_forwardA 3-meter-long 25 kg beam is supported by two cables as shown below. You can treat the beam as a slender rod.
