The following questions will you learn to apply the impulse-momentum theorem to the cases of constant and varying force acting along the direction of motion. first, let us consider a particle of mass m moving along the x axis. the net force f is acting on the particle along the x axis. f is a constant force. part a the particle starts from rest at t=0. what is the magnitude p of the momentum of the particle at time t? assume that t> 0. express your answer in terms of any or all of m, f, and t.

Which of the choices below is one of the primary gases found in the atmosphere? a. helium b. carbon dioxide c. nitrogen d. argon

Boxing gloves are padded to lessen the force of a blow. (a) calculate the force exerted by a boxing glove on an opponent’s face, if the glove and face compress 7.50 cm during a blow in which the 7.00-kg arm and glove are brought to rest from an initial speed of 10.0 m/s. (b) calculate the force exerted by an identical blow in the gory old days when no gloves were used and the knuckles and face would compress only 2.00 cm. (c) discuss the magnitude of the force with glove on. does it seem high enough to cause damage even though it is lower than the force with no glove?

The strong nuclear force acts over a small distance than the electrostatic force. true or false
