Question 11 Calculate the firing angle e of an anti-aircraft gun with a muzzle velocity of 600 m/s to score a direct hit on an aircraft flying horizontally at 1000 km/h. The gun is fired at the instant when the aircraft is directly overhead. If a near miss occurs when the shell is on its way up but a direct hit is scored when the shell is on its way down. Calculate the time t after firing for the hit to be scored if the altitude of the aircraft is 6000 m. 1000kmh 6000m u=600 m/s Hints : Let x be the horizontal distance the shell the aircraft.

The track for this racing event was designed so that riders jump off the slope at 35°, from a height of 2.25 m. During a race it was observed that the rider shown in Figure below remained in mid air for 0.75 s. Determine the speed at which he was traveling off the ramp, the horizontal distance he travels before striking the ground, and the maximum height he attains. Neglect the size of the bike and rider.
A ball is thrown vertically upward with an initial position is so= 10 m. The maximum height reached by the ball is 30m. Determine the initial velocity of the ball. Determine the time of flight when it returns to its original position. Determine the time of flight when it hits the ground. Determine the velocity just before it hits the ground. Check your answer using a different equation. Plot v(t) and s(t) from t = 0 to the time when the ball hits the ground.
Question- An aircraft flying at a height of 800m with uniform horizontal velocity of 360km/hr releases a bomb which hits a target on the ground.

Equations for the conservation of energy must be used, the speed that bodies of mass m1 and m2 have after they have traveled a distance "d". Consider the pulley with mass M and radius R. The masses are the same and the angles are different.
When a volleyball coach releases a volleyball from a height of 2 m above the gym floor, it falls to the floor and bounces back to two-thirds the same height. When it is in contact with the floor, the lower side of the ball is temporarily flattened. Suppose the maximum depth of the dent is 1 cm. (Assume the positive direction is upward.)1. Determine the acceleration of the ball (in m/s2) while it is in contact with the floor and compressing. (Indicate the direction with the sign of your answer.) 2. Determine the velocity of the ball (in m/s) as it leaves the floor on the rebound. (Indicate the direction with the sign of your answer.) 3. What If? If instead of dropping the ball, the coach throws it down (from some unknown height) with such a speed that it bounces back up to a height three times its original height, determine the new acceleration of the ball (in m/s2) while in contact with the floor and expanding. (Indicate the direction with the sign of your answer.)
A volleyball is hit when it is 4 ft above the groundand 12 ft from a 6-ft-high net. It leaves the point of impact withan initial velocity of 35 ft / sec at an angle of 27 and slips by theopposing team untouched. Suppose that the net is raised to 8 ft. Does this change things? Explain.
In the system shown, a spring is compressed and pushes a mass of 50Kg down the path shown with two different slopes. If the spring has a constant of 25 kN / m, what would have to be the deflection of the spring for the block to reach the limit at 2 m/s ? The coefficient of kinetic friction is 0.15 and assume that starting from rest to make the ideal system
