- A penny is dropped from the observation deck of the Empire State building (325.0 m above ground). With what velocity would it strike the ground if air resistance were negligible? Assume the free-fall acceleration g = 9.80 m/s2. Ignore air resistance. If the velocity is downward, enter a negative value and if the velocity is upward, enter a positive value.A diver steps off the cliffs at Acapulco, Mexico, 27.6 m above the surface of the water. At that moment, he activates his rocket-powered backpack horizontally, which gives him a constant horizontal acceleration of 5.7 m/s2 but does not effect his vertical motion. (For the following questions, ignore any effects of air resistance.) 1) (a) How long does he take to reach the surface of the water? (b) How far out from the base of the cliff does he enter the water, assuming the cliff is vertical? (c) Show that his fight path is a straight line. (Do this on paper. Your instructor may ask you to turn in your work.1. A car is parked on a cliff overlooking the ocean on an incline that makes an angle of 24.0° below the horizon- tal. The negligent driver leaves the car in neutral, and the emergency brakes are defective. The car rolls from rest down the incline with a constant acceleration of 4.00 m/s2 for a distance of 50.0 m to the edge of the cliff, which is 30.0 m above the ocean. Find (a) the car's position relative to the base of the cliff when the car lands in the ocean and (b) the length of time the car is in the air.
- A person falls from a height of 2.0m on earth (a=g=9.8m/s2). What acceleration is necessary for them to stop over 30 cm (assuming they bend their knees)? What if they don't bend their knees hence stop over a distance of 1 mm?A cargo helicopter, descending steadily at a speed of 3.8 m/s, releases a small package. Let upward be the positive direction for this problem. (a) If the package is 94 m above the ground when it is dropped, how long does it take for the package to reach the ground? (a) What is the initial velocity of the package? How does it compare to that of the helicopter? What is its sign? What about the magnitude and sign of the acceleration? s(b) What is its velocity just before it lands? (Indicate the direction with the sign of your answer.)Paul the polar bear is chillin’ on on iceberg and throwing snowballs straight up in the air near the Earth’s surface. What is the acceleration of the snowball when it reaches the maximum height? (Up is the +y^+y^ direction; no air resistance)
- A certain volcano on the Earth can eject rocks vertically to a maximum height H. How high (in terms of H) would these rocks go if a volcano on a planetary object ejected them with the same initial velocity? The accelerations due to the gravity on the Earth and the planetary object are 9.8m/s² and 3.1 m/s?, respectively. Neglect the effect of the air on both planets. 답:Mature salmon swim upstream, returning to spawn at their birthplace. During the arduous trip they leap vertically upward over waterfalls as high as 3.29 m. With what minimum speed (in m/s) must a salmon launch itself into the air to clear a 3.29-m waterfall? HINTA red ball is thrown down with an initial speed of 1.1 m/s from a height of 28 meters above the ground. Then, 0.5 seconds after the red ball is thrown, a blue ball is thrown upward with an initial speed of 24.3 m/s, from a height of 0.9 meters above the ground. The force of gravity due to the earth results in the balls each having a constant downward acceleration of 9.81 m/s?.
