Work and Forces in Particle Motion

H 6.12 1/1 point (graded) Consider a particle on which several forces act, one of which is known to be constant in time: F = (3N) } + (AN) }. As a result, the particle moves along a straight path from a Cartesian coordinate of (0m, 0m) to (5m, 6m). What is the work in N.m done by F? Enter your answer to two significant figures without unit. 39 V 39 Submit Show answer H 6.13 1/1 point (graded) The force F (x) varies with position, as shown below. Find the work done ( in J) by this force on a particle as it moves from x = 1.0m to z = 5.0m. Enter your answer to two significant figures without unit. F(x) (N) 6.0 4.0 20 0 2.0 -2.0 4,0 6.0 8.0 x(m) -40 8 V 8 H 6.14 1/1 point (graded) Consider a particle on which a force acts that depends on the position of the particle. This force is given by F = (2y) } + (3x) }. Find the work done (in J) by this force when the particle moves from Cartesian coordinate of (0m, 1m) to (5m, 1m). Assume that y(x) = 1.0. Enter your answer to two significant figures without unit. 10 V 10 H 6.15 1/1 point (graded) An 14-g bullet with a speed of 800 m/s is shot into a wooden block and penetrates 22 cm before stopping. What is the average force (in N) of the wood on the bullet? Assume the block does not move. Give your answer to two significant figures without units. 20363.64 >
