Just the answer for c please,
a is 6.27m/s and b is 6.1 m/s
P5 An iron sphere is thrown straight up from a height of 2 m with a velocity of 0.3 m/s. It falls back to ground and bounces. After the bounce, it momentarily comes to a stop at a height of 1.9 m, where it is caught (a) What is the speed of the ball when it first reaches the ground? (b) What is its speed when...
A ball is thrown up 90 feet in the air. it comes down, bounces, and then rises up to a height of 81 feet. Then it falls to its second bounce, and so on. Each time it falls, it bounces back to 90% of its previous height. (a) How high does the ball rise before the 30th bounce? (Please read the question carefully. If the question read “How high does the ball rise before the second bounce?” the answer would...
7.A ball is thrown straight up from waist height. After travelling up for a short distance it reverses direction and then comes back down and hits the ground. At which of the following times was its velocity zero? A. When the ball leaves the hand B. At its highest point C. When it returns to the height from which it was originally thrown D. Just before it hits the ground
A blue ball is thrown upward with an initial speed of 22.8 m/s, from a height of 0.6 meters above the ground. 2.8 seconds after the blue ball is thrown, a red ball is thrown down with an initial speed of 7.7 m/s from a height of 28.2 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/s2. ) What is the speed of the...
a ball whose mass is .35 kg falls from rest through a height of 5.3 m and then bounces back. it reaches a maximum height of 3.8 m after the bounce before falling to the ground again. from the beginning at 5.3 m to the height of 3.8 m after the bounce. the magnitude of its mechanical energy has changed by a) zero b) 13.0 J c) 0.52 J d) 5.15 J
A ball is thrown straight up into the air from the ground with initial velocity v0= 4 m/s, it reaches its apex and falls back down. Neglecting air resistance, how long does it take the ball to return to the ground?
A red ball is thrown down with an initial speed of 1.3 m/s from a height of 26 meters above the ground. Then, 0.4 seconds after the red ball is thrown, a blue ball is thrown upward with an initial speed of 23.9 m/s, from a height of 1 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/s2. What is the speed of the...
An object is thrown upward from 1 m above the ground. It travels vertically up, reaches a maximum height of 2.5 m above ground, falls back down, and is caught at exactly the same position it was thrown 1 s after it was thrown. What was the average velocity of the object? Click the answer you think is right 1.5 m/s 0 m/s 3 m/s
A red ball is thrown down with an initial speed of 1.2 m/s from a height of 25 meters above the ground. Then, 0.6 seconds after the red ball is thrown, a blue ball is thrown upward with an initial speed of 23.8 m/s, from a height of 0.8 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^2. 1)What is the speed of the...
