I need help with this problem A student in Physics 211 decides to do an experiment. They travel to a city and climb to the roof of a building that is 3.0 x 102 m tall. Then, at the same instant, they drop one rock while a second rock is thrown downward with an initial speed of 16 m/s. Assume both rocks experience negligible air resistance while falling. How much EARLIER does the thrown rock strike the ground? A) 1.1 s B) 1.5 s C) 1.4 s D) they land exactly at the same time
A pilot ejects from his aircraft and falls 80 m from the ground without friction. Whenhe opens his parachute, he decelerates at 3.5 m/s2. The pilot hits the ground at 5 m/s.How long was the pilot in the air and at what height did he begin his fall?
A 5m tall elevator travels uniformly up an elevator shaft at 8m/s. At some point in time, a bolt falls from the top of the elevator and falls freely down the shaft. You can ignore the effect of air resistance. How many seconds after the fall will the bolt pass the bottom of the elevator?
While standing at the edge of the roof of a building, a man throws a stone upward with an initial speed of 6.71 m/s. The stone subsequently falls to the ground, which is 16.7 m below the point where the stone leaves his hand. At what speed does the stone impact the ground? Ignore air resistance and use g = 9.81 m/s² for the acceleration due to gravity. impact speed: m/s How much time is the stone in the air? elapsed time: S
A tortoise and a hare are in a road race to defend the honor of their breed. The tortoise crawls the entire 1000 meters at a speed of 0.2 m/s. The rabbit runs the first 200 meters at 2 m/s, stops to take a nap for 1.3 hours, and awakens to finish the last 800 meters with an average speed of 3 m/s. Who wins the race and by how much time?
An object slides off a frictionless, horizontal table from a height of 1.40 m above the floor. Itstrikes the floor a distance of 1.88 m from the base of the table.a) Calculate the speed with which the object leaves the table.b) Calculate the velocity (magnitude and direction) of the object just before it strikes the floor.
A a vs. t graph is drawn for a car moving in one direction. The graph shows a horizontal line at a = 5 m/s2 from t = 0 s to t = 5 s. What is the velocity of the ball at t= 5 s? Assume the car is initially at rest. (Answer is given as 25m/s, just need help knowing how to solve it.)
A 5m tall elevator travels uniformly up an elevator shaft at 8m/s. At some point in time, a bolt falls from the top of the elevator and falls freely down the shaft. You can ignore the effect of air resistance. Assume that the bolt falls from the *wall* of the elevator shaft when it is level with the top of the elevator, and then falls freely without air resistance. How many seconds after the fall will the bolt pass the bottom of the elevator?
At t=0, a particle starts with an initial velocity of 10 i m/s and accelerates uniformly at (-2.0 i +4.0 J) m/s^2. What is the speed of particle at t=5s? 1- 32m/s 2- 30 m/s 3- 28 m/s 4- 20 m/s 5- 10 m/s
Ironman steps from the top of a tall building. He falls freely from rest to the ground a distance of hh. He falls a distance of h/h/ 4 in the last interval of time of 1.0 ss of his fall. Hint: First, compute the velocity when Ironman reaches the height equal to the distance fallen. This requires that you do the following: define origin as the bottom of the building. Then use x-x0 = -v0*(t-t0)-(1/2)g(t-t0)^2 where x=0 and x0= (distance fallen) and t-t0 is the time interval given. In this formulation, you are going to get magnitude of v0 since you already inserted the sign. You then insert v0 that you just calculated into the kinematic equation that involves v, g, and displacement (v^2-v0^2 = 2g(height-(distance fallen)), but now v (which is the final velocity is v0 from above) and v0 in this case is the velocity that the Ironman has when he begins to fall, which is 0. This gives a quadratic equation for height h, and you will need to use the binomial equation to solve for h.…
