A family is skating. The father (85 kg) skates
at 8.6 m/s and collides and sticks to the
mother (65 kg), who was initially moving
at 3.0 m/s and at 45° with respect to the
father's velocity. The pair then collides with their
daughter (30 kg), who was stationary, and the three slide
off together. What is their final velocity? (Enter the magnitude in
m/s and the direction in degrees with respect to the father's
initial velocity.)
magnitude = ?? m/s
direction = ?? ° with respect to the father's
initial velocity

A 10 kg mass with an initial velocity of 6 i m/s collides and sticks to a 5 kg mass with an initial velocity of - 5 j m/s. Find the direction (in degrees) of the final velocity of the two masses with respect to the direction of the x axis. (Note: take your calculated angle as positive.)

A 90kg hockey player is skating with the puck at 25m/s(north), When he collides with a second hockey player, this one with a mass of 95kg, who is skating 12m/s (west). The two players get tangled up on impact and move together. What is the velocity (magnitude and direction) of the two players after impact?!

A 62 kg man is ice-skating due north with a velocity of 6.6 m/s when he collides with a 43 kg child. The man and child stay together and have a velocity of 3.2 m/s at an angle of 33° north of due east immediately after the collision. What are (a) the magnitude and (b) the direction (as an angle measured from due East) of the child's velocity just before the collision?

A 1240 kg car traveling south at 24 m/s with respect to the ground collides with and attaches to a 2510 kg delivery truck traveling east at 16 m/s. A)Determine the direction of the velocity of the two vehicles when locked together just after the collision. Take east direction as zero angle. B)Determine the magnitude of the velocity of the two vehicles when locked together just after the collision.
