(c) When is the displacement of the boulder from its initial position zero? (d) When is the velocity of the boulder zero? (e) What are the magnitude and direction of the...
9) A 2 kg object is thrown vertically upward with an initial velocity of 10 m/s. (a) What is its velocity at a point halfway to the maximum height it will attain? (a) What is the total time required for it to return to its initial position? (c) What is its acceleration at the maximum height? (d) What is its average speed during the complete trip? (neglect air resistance
a stone is thrown vertically upwards with an initial speed of u, its vertically displacement s after an elapsed time t is given by the formular s= ut - gt^2/2 where g is the acceleration due to gravity air resistance is ignored, calculate the value of s over a period of 12.3 seconds at intervals of 0.1 seconds . and plot the distance time graph over this period by writing matlab/ octave code that implements and solves rhis problem.
#3) A walnut is shot nearly vertically upward from a point near the edge of a tall building from a cannon. It just misses the edge on the way down (when it is in free fall) and passes a point a distance 40.0 m below its starting point at a time 5.00 s after it leaves the cannon barrel. Air resistance may be ignored. Report answers to the below questions to 3 sig figs. Set downward as the negative direction....
You throw a ball upward with an initial speed of 3.0 m/s from an initial height of 1.5 m. After you throw the ball, its acceleration is 9.81 m/s2 downward. Taking upward to be the positive direction, write the position-time equation for the ball's motion. Express your answer in terms of t. t is expressed in seconds.
An egg is thrown nearly vertically upward from a point near the cornice of a tall building. It just misses the cornice on the way down and passes a point a distance 48.0 m below its starting point at a time 5.00s after it leaves the thrower's hand. Air resistance may be ignored. part A: What is the initial speed of the egg? v= m/s part B: How high does it rise above its starting point? h= m part C:...
Free-fall notion 1. A ball is thrown vertically upward at an initial speed of 49 m/s. Assume that the ball leaves the hand when it is 15 m above the ground (about the height of Kirkbride), and that the effects of air resistance can be ignored. Choose your landmark to be the ground; then at t -0, yo- +15 m, Vyo +49 m/s a. 5 pts) How fast is the launch speed in mph? Do you think this is a...
A rock is thrown vertically upward with a speed of 15 m/s. What are its speed and direction 2 s later? a. 10 m/s upward b. 5 m/s upward c. zero d. 5 m/s downward
An egg is thrown nearly vertically upward from a point near the cornice of a tall building. It just misses the cornice on the way down and passes a point a distance 43.0 m below its starting point at a time 5.00 s after it leaves the thrower's hand. Air resistance may be ignored. A) What is the initial speed of the egg? Express your answer in meters per second. B)How high does it rise above its starting point? Express...
A 0.26-kg rock is thrown vertically upward from the top of a cliff that is 32 m high. When it hits the ground at the base of the cliff, the rock has a speed of 33 m/s . Part A Assuming that air resistance can be ignored, find the initial speed of the rock.(Express your answer using two significant figures.) Part B Find the greatest height of the rock as measured from the base of the cliff. (Express your answer...
