As shown, a projectile of weight W is fired from point O perpendicular to the incluned plane. It lands at A a distance of 70m from O as measured along the inclined plane, which of the following gives the maximum height "h" reached by the projectile? Choices: 33.04m 30.43m 43.30m 34.33m 40.33m 24.40m
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).
