Homework Answers
a) let the speed of the combined mass after the collision is v
Using conservation of momentum
0.75 * (1.2 i - 3.4 j) + 2.4 * (0.58 j) = (0.75 + 2.4) * v
solving for v
v = 0.29 i - 0.37 j
speed of combined mass = sqrt(0.29^2 + 0.37^2)
speed of combined mass = 0.466 m/s
the speed of combined mass is 0.466 m/s
b)
for the angle
angle of the trajectory = atan(-0.37/0.29)
angle of the trajectory = - 52.1 degree
the angle of trajectory is - 52.1 degree

A ball of mass m moving with velocity v_i_vec strikes a vertical
wall. The angle between the ball's initial velocity vector and the
wall is theta_i as shown on the diagram, which depicts the
situation as seen from above. The duration of the collision between
the ball and the wall is Deltat, and this collision is completely
elastic. Friction is negligible, so the ball does not start
spinning. In this idealized collision, the force exerted on the
ball by the...

A block of mass m1 = 1.10 kg moving at v1 = 1.20 m/s undergoes a completely inelastic collision with a stationary block of mass m2 = 0.900 kg . The blocks then move, stuck together, at speed v2. After a short time, the two-block system collides inelastically with a third block, of mass m3 = 2.40 kg , which is initially at rest. The three blocks then move, stuck together, with speed v3. Assume that the blocks slide without...

Ball 1 has mass m and is moving to the right at v0 = 7.00 m/s. It collides with ball two, of mass 3m, which is at rest. After the collision ball 1 has a velocity of v1 = 4.50 m/s at an angle of ? = 30.0° relative to its original direction. Determine the magnitude and direction of the velocity, v2, of ball 2 after the collision.
