A 1.2-kg spring-activated toy bomb slides on a smooth surface along the x-axis with a speed of 0.50 m/s. At the origin 0, the bomb explodes into two fragments. Fragment 1 has a mass of 0.40 kg and a speed of 0.90 m/s along the negative y-axis. A. Find the angle θ, made by the velocity vector of fragment 2 and the x-axis. B. What is the energy released by the explosion?

Topic - center of mass and linear momentum: A 15 kg package is moving at a speed of 10.0m/s vertically upward along a y-axis when it explodes intro three fragments: a 2.00kg fragment is shot upward with an initial speed of 20.0m/s and a 3.00 kg fragment is shot in the positive direction of a horizontal x axis with an initial speed of 5.00m/s. Find a) the speed of the third fragment right after the explosion. b) the total kinetic...
A 3.0 kg block slides along a horizontal frictionless surface with a speed of 9.8 m/s. The block makes a smooth transition to a frictionless ramp inclined at an angle of 35.0
A leggs of mass 12g slides along a frictionaless surface with an initial speed of 2.6 m/s . If the leggs slides up a ramp and comes to rest, at what height does the leggs come to rest? If the leggo slides into an uncompressed spring (k=6.2 kg/s^2) on a smooth horizontal surface, wnat is the maximum compression of the pring by the leggo? If the leggo sldes into an uncopressed spring (6.2 kg/s^2) on a smooth horizontal surface, what...

(3) A particle of mass 3 kg travels along the y-axis with a speed of 5 m/s. Then the particle explodes into two pieces. One piece moves as: m = 2 kg = 3i+2j m/s (a) Find the velocity (vector) of the other piece. (b) Find the impulse, J (a vector), on the 2 kg piece. (c) Find the impulse, J (a vector), on the other piece. (d) Considering the energy, what can you say about the explosion?
A 7.0 kg toy car can move along an x axis. The figure gives Fx of the force acting on the car, which begins at rest at time t = 0. The scale on the Fx axis is set by Fxs = 4.0 N. IN UNIT VECTOR NOTATION PLEASE, what is P at (a)t = 2.0 s and (b)t = 7.0 s,(c) what is v at t = 2.0 s? PLEASE PUT ANSWER IN UNIT VECTOR NOTATION F (N) -F3S
In the figure, particle 1 of mass m1 = 3.3 kg slides rightward along an x axis on a frictionless floor with a speed of 5.0 m/s. When it reaches x = 0, it undergoes a one-dimensional elastic collision with stationary particle 2 of mass m2 = 4.3 kg. When particle 2 then reaches a wall at xw = 73 cm, it bounces from the wall with no loss of speed. At what position on the x-axis does particle 2...
