Find the speed required to throw a ball straight up and have it return 6 seconds later. How high does the ball go?
a. Find the speed required to throw a ball straight up and have it return 6 seconds later. Neglect air resistance. b. How high does the ball go? Please Help!! Thanks!! :)
2) You throw a ball straight up with an initial velocity 15.0 m/s a) How high does it go? Ignor e the air resistance. (1 mark) b) How long does it take for the ball to reach its maximum height? (1 mark) What is the ball velocity when the ball is 6.00 m above the initial throwing point? c) (1 mark) What is the velocity of the ball when it back to initial point? (1 mark) d) 2) You throw...
You throw a ball straight up from the ground (? = 0) with an initial speed of 20 m/s. At the same time (? = 0), another ball is dropped from a building that is 15 m high. How long will it take for the two balls to be exactly the same height off the ground?
I throw a ball straight up in the air with a speed of 15 m/s. It leaves my hand at a height of y = 0 m. a) How high will it go? b) How long does it take to return to its initial height?
A ball thrown straight up takes 6.20 seconds to go up and come back down to its starting point. Neglecting air resistance, how high (in m) does it go?
You throw a rock straight up with a speed of 10 m/s. How long will it take to reach the top of its path? Neglect the effects of air resistance in this and the next question. a. 1.02 s b. 0.51 s c. 1.42 s d. 2.84 s
You throw a ball straight up. The ball has an initial speed of 11.2 m/s when it leaves your hand. A) What is the maximum height the ball reaches relative to the throwing point. B) How long does it take the ball to reach this height? C) What is the position of the ball at t=2s? D) At what height does the ball have a speed of +5m/s?
You throw a ball straight up, and it lands with 2/3 the speed with which you threw it. What fraction of the initial kinetic energy was lost during the time the ball was in the air?
If a ball is thrown straight up at 20 m/sec and takes 4.08 seconds to return to your hand, how high did the ball go?
s. In the previous problem, if the ball hits the ground 4.4 seconds later, how high to the nearest tenth of a meter is the cliff? (Il) Three vectors are shown in Fig. 3-32. Their magnitudes are given in arbitrary units Determine the sum of the three vectors Give the resultant in terms of (a) components (b) magnitude and angle with the a asis. 6.
