Question 3 1 pts A rock is thrown upward from the edge of a cliff that is 20 m high. The object rises 15 m and then falls to the ground. If the positive direction of the x is up, what is the rock's displacement? O 20 m 0-15 m -20 m O 55 m Question 4 1 pts A 4.4-kg mass is falling starting from rest at a height of 22 m. How much time does it take for...
Suppose f is a quadratic function that has roots at I = - 4 and I = 8, and f(0) = 16. We will write a function formula for f. a. Sketch a graph of f based on the information you are given. b. We can write f as f(x) = c(x - 1)(x - ) where x < , and c is some constant number What are the values of 3, and az? O2 = -2/4(x+4)(x-8) Preview Preview c....
Problem 7. A rock is thrown vertically upward with a speed of 19.0 m/s from the roof of a building that is 50.0 m above the ground. Assume free fall. 1. In how many seconds after being thrown does the rock strike the ground? 2. What is the speed of the rock just before it strikes the ground? 3. What is rock's position 2.00 seconds after the throw? 4. What is rock's velocity after its displacement of -20.0m?
A rock thrown vertically upward from the surface of the moon at a velocity of24 m/sec reaches a height of s=24t-0.8t^2 meters in t seconds.a) Find the rock’s acceleration and velocity at time t.b) How long does it take the rock to reach its highest point?c) How high does the rock go?d) How long does it take the rock to reach half its maximum height?e) How long is the rock aloft?
Two Thrown Balls 1 2 3 45678 A blue ball is thrown upward with an initial speed of 19.8 m/s, from a height of 0.6 meters above the ground. 2.4 seconds after the blue ball is thrown, a red ball is thrown down with an initial speed of 8.9 m/s from a height of 22.3 meters above the ground. The force of gravity due to the earth results in the bals each having a constant downward acceleration of 9.81 m/s2....
At time t = 0 s, a rock is thrown vertically upward from the ground. At time t = 1.6 s, it passes the top of a tall tower. 0.80 s later, it reaches its maximum height. Q)How fast is the rock moving as it passes the top of the tower? A car moving with constant acceleration covers the distance between two points 120 m apart in a time of 8.0 s. Its speed at the second point is 12...
A rock is thrown vertically upward from ground level at time t = 0. At t = 1.8 s it passes the top of a tall tower, and 1.2 s later it reaches its maximum height. What is the height of the tower?
1. If a rock is thrown into the air at a 30° degree angle with an velocity of 20m/s, what is the maximum height reached by the rock? 2. If a bullet is fired from an gun at a 60° angle with a velocity of 300m/s, how far does it reach before hitting the ground? 3. If the velocity function of an object is t)(t2-1)i+ (2t+2)js what is the instantancous speed of the object at t 2s 4. If the...
A rock is thrown vertically upward from ground level at time t = 0. At time t = 1.4 s it passes the top of a tall tower, and 1.2 s later it reaches its maximum height. What is the height (in m) of the tower?
