A cannon is fired horizontally from a platform (see figure). The
platform rests on a flat, icy, frictionless surface. Just after the
shell is fired and while it is moving through the barrel of the
gun, the shell (mass 3.1 kg) has an acceleration of +2700
m/s2. At the same time, the cannon has an acceleration
of -0.83 m/s2. What is the mass of the cannon?

A cannon is fired horizontally. Before the firing, the cannon (which is mounted on a massive wooden base) was initially at rest on a flat, icy, surface; any friction between the base of the cannon and the ice is small enough to be ignored. Just after the explosion in the cannon barrel, the shell (with a mass of 3.3 kg) is moving through the barrel of the gun with a speed of 2450 m/s. At that same instant of time,...

7. Figure 4 shows a cannon. When the gun is fired, high pressure gasses accelerate the projectile. The reaction force pushes the gun barrel in the opposite direction to the projectile. The gun barrel is made to translate backwards against a critically damped spring-damper system called the recoil mechanism. The mass of the gun barrel the recoi mechanism is 500 kg and the recoil spring stiffness is 10 kN/m. Upon firing, the gun recoils 0.4 m. Find (a) the damping...

An astronaut weighs 850 N on the Earth’s surface. When the astronaut lands on Planet X, she weighs 190 N. To the nearest tenth of a m/s2, what is the acceleration of gravity on Planet X? (hint: first find her mass!) An elevator car loaded with two passengers has a mass of 1200 kg. What tension must be applied by the elevator cable to give the car an acceleration of 1 m/s2 upward?

A 4.25-g bullet traveling horizontally with a velocity of magnitude 375 m/s is fired into a wooden block with mass 1.10 kg, initially at rest on a level frictionless surface. The bullet passes through the block and emerges with its speed reduced to 126 m/s. Part A How fast is the block moving just after the bullet emerges from it? Express your answer in meters per second.

In Figure (1), a 3.50 g bullet is fired horizontally at two
blocks at rest on a frictionless table. The bullet passes through
block 1 (mass 1.20 kg) and embeds itself in block 2 (mass 1.85 kg).
The blocks end up with speeds v1 = 0.510 m/s and v2 = 1.38 m/s (see
Figure (2)). Neglecting the material removed from block 1 by the
bullet, find the speed of the bullet as it (a) leaves and (b)
enters block 1....

A cannonball is fired horizontally from the top of a cliff. The cannon is at height H = 70.0m above ground level, and the ball is fired with initial horizontal speed v0. Assume acceleration due to gravity to be g = 9.80m/s2 . Part A Assume that the cannon is fired at time t=0 and that the cannonball hits the ground at time tg. What is the y position of the cannonball at the time tg/2? Answer is 52.5 Part...
