You throw a 87.6-g pebble vertically up in the air, by supplying it with the initial kinetic energy of 1.6 J. How high up did you throw the pebble?

You shoot a 54-g pebble straight up with a catapult whose spring constant is 310 N/m. The catapult is initially stretched by 0.30 m. How high above the starting point does the pebble fly? Ignore air resistance.
A slingshot obeying Hooke’s law is used to launch pebbles vertically into the air. You observe that if you pull a pebble back 11.2 cm against the elastic band, the pebble goes 5.7 m high. A)Assuming that air drag is negligible, how high will the pebble go if you pull it back 22.4 cm instead? B)How far must you pull it back so it will reach 11.4 m ? C)If you pull a pebble that is twice as heavy back...
You throw a ball vertically up into the air with a velocity of 5 m/s. What is its acceleration just as it leaves your hand? What is its velocity when it reaches its maximum height? What is its acceleration when it reaches its maximum height?
Your favorite professor decided to throw in the air a marker above his head (vertically). If the marker leaves his hand at a height of 1.2 m from the ground with an initial velocity of 20 m/s, when would the marker reach the highest point in the air (1.6 m from the ground)?
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?
Shot a bullet vertically up in the air and measured how much time it took to fall to the ground. They measured the time of flight to be 1 minute 50 seconds. The air resistance significantly affects the motion (especially at high velocities) but for the sake of calculations, lets ignore this effect for now. 1) How high did the bullet reach? 2) Can you calculate the initial velocity of the bullet? 3)The bullet was just falling from the sky....
43. Analyze You throw a ball straight up into the air. ches a maximum height and returns to your hand. what location(s) is the kinetic energy of the ball (a) a maximum and (b) a minimum? At what location(s) is the potential energy of the ball (c) a maximum and (d) a minimum? At
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...
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?
3. You throw a ball into the air, and catch it 5s later at the same height at which it was thrown. (4 marks) What was the initial velocity of the ball? And how high did the ball go?
