1. A small coin, initially at rest, begins falling. If the clock starts when the coin begins to fall, what is the magnitude of the coin's displacement between ?1=0.404 s and ?2=0.673 s? Δ?= 2. You attach a meter stick to an oak tree, such that the top of the meter stick is 1.67meters above the ground. Later, an acorn falls from somewhere higher up in the tree. If the acorn takes 0.121 seconds to pass the length of the...
PLEASE ANSWER ALL 3 QUESTIONS ALL DIFFERENT PROBLEMS!!! 1. In April 1974, Steve Prefontaine completed a 10 km10 km race in a time of 27 min27 min, 43.6 s43.6 s. Suppose "Pre" was at the 8.27 km8.27 km mark at a time of 25.0 min25.0 min. If he accelerated for 60 s60 s and then maintained his increased speed for the remainder of the race, calculate his acceleration over the 60 s60 s interval. Assume his instantaneous speed at the...
In a free-fall experiment, an object is dropped from a height of h = 144 feet. A camera on the ground 500 ft from the point of impact records the fall of the object (see figure). 500 ft Not down to scale (a) Find the position function that yields the height of the object at time t assuming the object is released at time t = 0. h(t) = At what time will the object reach ground level? (Round your...
. An object is launched with 47 m/s vertically upward. At what height is the object after 3 s. What is the velocity of the object after 3s?
A rocket blasts off vertically from rest on the launch pad with a constant upward acceleration of 2.60 m/s2 .At 30.0 s after blastoff, the engines suddenly fail, and the rocket begins free fall. What is the height of the rocket when the engine fails? Find the magnitudes of the rocket's velocity and acceleration at its highest point. How long after it was launched will the rocket fall back to the launch pad?
Problem 2 (50 points) An object of mass m is launched from the ground at 30 degrees to the horizontal with an initial velocity v. After achieving a height of 10 m it begins to fall. Precisely at this point, it also explodes into two pieces of equal mass; these two pieces initially move horizontally. One of the pieces comes back and lands precisely where the object started out. (a) What was the y component of the initial velocity v?...
