Two objects (object A and object B) are moving with constant velocities (VA=30(m/s), VB=40(m/s)) in the same direction. Object B is behind object A. At the moment that the distance between them is 15(m) object A accelerates with aA = 1 (m/s^2) and object B decelerates with aB = -3(m/s).
Are they going to hit each other? (show your work)

Two bodies, A and B each of mass 2.0 kg moving with velocities vA = (2.0i ˆ + 5.0j) m/s and vB = (1.0i ˆ – 5.0j) m/s collide and stick together. After the collision, what is the velocity of the composite object?
Two identical hockey pucks
moving with initial velocities vA and vB collide as shown. If the
coefficient of restitution is e = 0.79, determine the velocity of
each puck just after impact. Also calculate the percentage loss n
of system kinetic energy.

Two objects are moving in the xy-plane. Object A has a mass of 3.2 kg and has a velocity vA = < 2.3 m/s, 4.2 m/s > and object B has a mass of 2.9 kg and has a velocity vB = < -1.8 m/s, 2.7 m/s > . What is the total momentum of the system? A uniform sphere of radius 2R has a spherical cavity of radius R cut out of it. The center of the cavity is...
H. Two objects start moving at the same time. Object A is initially at x x = 8 m and starts moving to the left at constant speed of 2 m/s and object B is initially at x2 m and starts moving to the right at a 1-1-1- constant speed of 3 m/s. Use the coordinate axes on the right to plot the position vs. time for both objects (for at least 4 seconds) then use your plot to identify...

An object is originally moving at 3.5 m/s in the negative x direction with a constant acceleration of 2.4 m/s2 in the negative x direction for 5.1 seconds. Then (immediately) a constant acceleration is applied to in the positive x direction. After some time, the average velocity for the entire trip is 0 m/s., and at that time, the object is moving at 61.2 m/s in the positive x direction. How long was the acceleration applied in the positive x...

1. A 20 Kg cart moving at 10 m/s collides with a 10 Kg cart moving at 20 m/ s. The two carts stick to each other after the collision. Calculate the final speed of the carts just after the collision if () They were moving in the same direction direction (i.e. thefaster bumped the slower from behind) (ii) They were moving at 90° respect to each other. (ii) They were moving at 30° respect to each...
1. An object is originally moving in the +x direction at 16 m/s and a constant acceleration is applied to it. When it is at a displacement of 7 meters in the +x direction it is moving in the -x direction at 6 m/s. What is the acceleration of the object in m/s2? If in the -x direction, include a negative sign. 2. An object travels in the +x direction for 6 meters for 3.4 seconds and then, immediately, changes...
