Find the speed required to throw a ball straight up and have it return 6 seconds later
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?
5. A football is kicked straight up into the air and hits the ground 4.7 seconds later. There is no air resistance. A. How long does it take to reach the highest point? B. What is its velocity at its highest point? C. How high does it rise? D. With what speed did the ball leave the foot? E. What is the speed of the ball just before it hits the ground?
throw a ball straight up into the air with initial velocity vi. (neglect air resistance). how long will it take for the ball to come back to its initial position? what is the maximum height the ball reaches?
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...
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?
You throw a ball straight upward. Part A Compared with its initial speed when thrown, how fast does it return to its starting point? Answer this for the case of no air resistance. The ball returns much faster than it was thrown. The ball returns slower than it was thrown. The ball returns as fast as it was thrown. Part B Answer this for the case where air resistance does affect motion. The ball returns as fast as it was...
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?
Playing shortstop, you pick up a ground ball and throw it to second base. The ball is thrown horizontally, with a speed of 26 m/s, directly toward point A (Figure 4-16). When the ball reaches the second baseman 0.40 s later, it is caught at point B. (Neglect air resistance.) Figure 4-16 (a) How far were you from the second baseman? m (b) What is the distance of vertical drop, AB? m
A ball is thrown straight down at 1.50 m/'s from a tall tower. Two seconds (2.00 s) later a second ball is thrown straight up at 4.00 m/s. How far apart are the two balls 4.00 s after the second ball is thrown? Ignore the effects of air resistance. Example 2-9
