two bombs of 20 kg and 30 kg are thrown from a cannon with the same velocity in the same direction
The cannon with mass of 10 t (ton) fires the missile with mass of 30 kg, at an angle of 60° (degrees). Calculate the velocity of the missile in regard to the ground, if the cannon is thrown back at a velocity of 3 m/s.
Cannon A shooots a cannon ball in the vertical direction. At the same moment, Cannon B shoots a cannon ball 60 above the horizontal. How many timesgreater does the velocity of cannon B need to be in order for the two cannon balls to land at the same time? Thanks!!!
a ball with mass 0.15 kg is thrown upward with initial velocity 20 m/sec from the roof of a building 30 m high. there is a force due to air resistance of |v|/30, where velocity v is measured in m/sec.a. find the maximum height above the ground the ball reaches.b. find the time the ball hits the ground.you cannot use the kinematic equations.
3. A water balloon is thrown vertically up with the initial velocity 20 m/s from a balcony 30 m above the ground. (a) What is maximum height above the ground the balloon will reach? (b) How much time will it take to reach the maximum height? (c) How much time will it take to reach the ground? (d) What is the balloon's velocity at the instant just before it hits the ground? (Be sure to include the correct signs)
A 500 kg cannon fires a 2.5 kg projectile with a velocity of 400 m/s parallel to the ground. The projectile hits a target which is 120 m away from the cannon. What is the recoil speed of the cannon?
A cannon is adjusted so that the barrel is horizontal to the ground. The opening of the barrel is 2.6 m off the ground as shown in the figure below, A cannon ball of mass 20 kg is fired across a flat open field and it travels a distance of 70.0 m before hitting the ground.a) Calculate the time for the ball to travel from the cannon to the point just before it hits the ground.b) Calculate the velocity with...
1. A ball is thrown with an initial velocity of 25.0 m/s in a direction that makes a 32.0° angle with the horizontal (Assume it was thrown from ground level). a. What is the maximum height of the ball relative to the ground? b. What is the velocity (magnitude and direction) of the ball att-0,708 s
A 75 kg mass is shot from cannon straight up with an initial velocity of 20m/s off a bridge that is 150 meters above the ground. If air resistance is given by 5v determine the velocity of the mass when it hits the ground.
A snowball is thrown off the edge of a 20 m tall building. It is thrown upward with an initial velocity in the y direction of 15 m/s and a velocity in the x direction of 5 m/s. Sketch the trajectory of the snowball from the time it is thrown until it hits the ground. Explain your trajectory 8. 9. At what angle above horizontal is the initial velocity of the snowball? 10. Atwhat speed was the snowball thrown? 11....
A stone is thrown from the top of a building with an initial velocity of 21.5 m/s straight upward, at an initial height of 51.7 m above the ground. (a) Determine the time needed for the stone to reach its maximum height. (b) Determine the maximum height. (c) Determine the time needed for the stone to return to the height from which it was thrown, and the velocity of the stone at that instant. (d) Determine the time needed for...
