A battleship simultaneously fires two shells toward two identical enemy ships. One shell hits ship A, which is close by, and the other hits ship B, which is farther away. The two shells are fired at the same speed. Assume that air resistance is negligible and that the magnitude of the acceleration due to gravity is g. * What shape is the trajectory (graph of y vs. x) of the shells? a.straight line b.parabola c.hyperbola d. The shape cannot be...

019 10.0 points A cannon fires a 0.579 kg shell with initial velocity Vi-11 m/s in the direction θ 43° above the horizontal. The shell's trajectory curves downward be- cause of gravity, so at the timet 0.55 s the shell is below the straight line by some vertical distance ΔΙι Find this distance Ah in the absence of air resistance. The acceleration of gravity is 9.8 m/s2. Answer in units of m

A shell is shot with an initial velocity
of 25 m/s, at an angle of
= 57° with the horizontal. At the top of the trajectory, the shell
explodes into two fragments of equal mass (see the figure). One
fragment, whose speed immediately after the explosion is zero,
falls vertically. How far from the gun does the other fragment
land, assuming that the terrain is level and that air drag is
negligible?

A mortar fires a shell of mass m = 1.79 kg at speed v0. The shell explodes at the top of its trajectory (shown by a star in (Figure 1)) as designed. However, rather than creating a shower of colored flares, it breaks into just two pieces, the smaller one of which has a mass 0.240 kg . If there had been no explosion, the shell would have landed a distance r = 172 m from the mortar. Both pieces land at...

A shell is shot with an initial velocity 0 of 20 m/s, at an angle of θ0 = 60° with the horizontal. At the top of the trajectory, the shell explodes into two fragments of equal mass . One fragment,whose speed immediately after the explosion is zero, falls vertically. How far from the gun does the other fragment land, assuming that the terrain is level andthat air drag is negligible?

A mortar fires a shell of mass m at speed v0. The shell explodes at the top of its trajectory (shown by a star in the figure) as designed. However, rather than creating a shower of colored flares, it breaks into just two pieces, a smaller piece of mass 15m and a larger piece of mass 45m. Both pieces land at exactly the same time. The smaller piece lands perilously close to the mortar (at a distance of zero from...

Problem 2: I throw a ball, mass m-5.0kg, at an initial speed of 3.0m/s, at an initial height of 1.7m, but at an angle of 37' with respect to the horizontal. It lands on the ground, at a final height of zero. (a) What is the initial velocity? (This is a VECTOR. Define ti as the horizontal, and +j as the vertical.) (b) What is the time when the ball obtains its maximum height? (c) What is the maximum height...

40. A projectile is launched from the top of a building with an initial velocity of 10.0 m/s at an angle of 42.0 below the horizontal. The building is 34.0 meters tall, and it stands on level ground. Air resistance is negligible. Calculate (a) the distance traveled horizontally by the projectile by the time it hits the ground, and (b) the magnitude and direction of the projectile's velocity at the instant it arrives at the ground.
