A hunter fired on a bird lurking on the top of a tree at an angle of 45o with the horizontal butnarrowly misses his target by some tens of centimeters. At the instant the bullet is verticallyabove the tower location, the bird incidentally flew horizontally to the right in the vertical planeof the projectile.(Note: The tip of the rifle is 1.5 m above the ground.)
Two spheres A and B (of mass m each) were fired vertically from the ground with different initial velocities at different times. When sphere A reached its summit, sphere B, with an upward velocity of 10.76 m/s, created a head-on collision with A. The impact caused sphere A to break into two pieces, each of mass m/2. Knowing one-piece reached Point C and the other piece reached point D after the collision, determine: (a) the velocity of sphere B after the collision; (b) the angle θ and the speeds of the two pieces after the collision; and (c) the force exerted by sphere A on B if the collision occurred in 0.001s.

A ball is thrown upwards from a cliff 100m high with an initial velocity of 100m/sec at 30 degrees with the horizontal. Determine: a) the maximum height reached b) the range c) location after 9.5 seconds (reckoned from the ground) d) velocity after 10.1 seconds.
A sight is taken with an Engineer's Level at rod held 200 meters away and an initial reading of 2.3 meters is observed. The bubble is then level through 7 spaces on the level tube, and the rod reading is 1.8 meters. One division in the level tube is equal to 0.6 mm. c. What is the total distance moved by the bubble? Answer seconds d. What is the difference in rod readings? Answer meters e. What is the subtended angle by the line of sights? Answer meters Next QuestionNext
A small projectile is fired vertically downward into a fluid medium with an initial velocity of 60 m/s. Due to the drag resistance of the fluid the projectile experiences a deceleration of a = (-0.4v3) m2, where v is in m/s. Determine the projectile’s velocity and position 4 s after it is fired. Answer: v = 0.559 m/s, ↓, s = 4.43 m
Read the question carefully and give me all right solutions with clear calculations. A jet is issued from the side of a tank under a constant head of 4.69m. The side of the tank has an inclination of 1H to 1V. The total depth of water in the tank is 7.48m. Neglecting air resistance and assuming Cv=0.987, determine the following. a. the maximum height to which the jet will rise b. the point it strike a horizontal plane 1.69m below the bottom of the tank. c. the velocity of the jet as it strikes the ground.
A projectile is fired with an initial velocity of 150m/s off the roof of the building. Determine the maximum height reached by the projectile measured from the ground.note: use 3 decimal places
The object is fired vertically upward from the ground, with an initial velocity of 50 m/s. The mass of the object is 10 kgs. Determine the maximum height to which it will travel if atmospheric resistance is neglected, and the maximum height to which it will travel if atmospheric resistance is being considered as FD = 105 N
A nozzle inclined at an angle of 60° with the horizontal issues a 114.31-mm diameter water jet at the rate of 14 m/s. Neglecting air resistance, what is the area (in m2) of the jet at the highest point of the projectile? Round off to four decimal places.
Collars A and B are connected by a 525 mm wire and can slide freely, without friction, on the rods. If the force P = 370j [N] is applied to collar A and the system is in balance, calculate the intensity of the Force Q to keep the system balanced, when y = 155mm.
