A ball is thrown with in an initial velocity of 31.4 m/s straight up. What is...
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 ball is thrown vertically upwards with an initial velocity of 18.80 m/s, from the ground. How long is the ball in the air? (Neglect air resistance.) What is the greatest height reached by the ball? Calculate the time at which the ascending ball reaches a height of 12.8 m above the ground. A rocket, initially at rest on the ground, accelerates straight upward with a constant acceleration of 53.0 m/s^2, until the fuel is used up after 6.80s. What...
A ball is thrown straight upward in the air at a speed of 15.0 m/s. Ignore air resistance. a) What is the maximum height the ball will reach? b) What is the speed of the ball when it reaches 5.00 m?c) How long will the ball take to reach 5.00 m above its initial position on the way up? d) How long will the ball take to reach 5,00 m above its initial position on its way down?
Two throw A blue ball is thrown upward with an initial speed of 22.2 m/s, from a height of 0.8 meters above the ground. 2.7 seconds after the blue ball is thrown, a red ball is thrown down with an initial speed of 9.2 m/s from a height of 27.8 meters above the ground. The force of grandly due to the earth results in the balls each having a constant downward acceleration of 9.81 m/s^2. What is the speed of...
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?
A ball is thrown straight up into the air with an initial speed of 5 m/s and is then caught as it comes back down to the pitcher. How long does the ball remain in the air, in seconds?
A 0.11 kg ball of dough is thrown straight up into the air with an initial speed of 17 m/s. The acceleration of gravity is 9.8 m/s 2 . What is its momentum halfway to its maximum height? Answer in units of kg m/s.
3. A ball is thrown straight up, reaches a maximum height, then falls to its initial height. Make a statement about the direction of the velocity and the acceleration as the ball is coming down. (1 mark) a) Both its velocity and its acceleration point upward b) Its velocity points downwards and its acceleration points upwards c) Its velocity points upwards and its acceleration points downwards d) Both its velocity and its acceleration point downwards. 4. A man stands on...
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...
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...
