The resistance of the first block is assumed to be proportional to the bullet speed, that for the second block is proportional to vž, and that for the third block is proportional to v². If you fire at these blocks one by one with the same initial speed of vo for your bullets, compute the farthest the bullet can travel in each of these all three cases.

Concept explainers

Rigid Body

A rigid body is an object which does not change its shape or undergo any significant deformation due to an external force or movement. Mathematically speaking, the distance between any two points inside the body doesn't change in any situation.

Rigid Body Dynamics

Rigid bodies are defined as inelastic shapes with negligible deformation, giving them an unchanging center of mass. It is also generally assumed that the mass of a rigid body is uniformly distributed. This property of rigid bodies comes in handy when we deal with concepts like momentum, angular momentum, force and torque. The study of these properties – viz., force, torque, momentum, and angular momentum – of a rigid body, is collectively known as rigid body dynamics (RBD).

Question

Consider shooting a bullet of mass m to three different big blocks. The
resistance of the first block is assumed to be proportional to the bullet speed, that
for the second block is proportional to vž, and that for the third block is
proportional to v². If you fire at these blocks one by one with the same initial speed
of vo
for your bullets, compute the farthest the bullet can travel in each of these all
three cases. Note that the gravitational force for this problem is negligible.

You decide to launch a rockof mass m1 using a tube containing a spring of spring constant k. When the spring is at equilibrium, it fills the entire tube. To launch a rock, you push it into the tube, compressing the spring a distance d, at which point a locking mechanism holds the spring(and the rock) in place. When the lockis released, the spring pushes the rock to the end of the tube where it will be launched into the air. The coefficient of kinetic friction between the rock and the inside surface of the tube is given by μk. You setup the launcher at an angle q above the horizontal with the spring end buried such that when the spring is compressed and locked, the rock is at ground level. a)Find the work done on the rock by non-conservative forces as it moves from the point of release to the end of the tube. Express your answer in terms of μk, m1, q, d, and any necessaryconstants. b) Find the velocity of the rockvfas it exits the launch tube in terms of μk, k, m1, q, d, and any…
