3. You are standing on a frictionless ice parking lot. Your mass is 70.0 kg . Your friend throws a 0.400 kg ball to you horizontally at a speed of \( 10.0 \mathrm{~m} / \mathrm{s} \). (a) what speed do you move if you catch the ball? (b) what speed do you move if the ball bounces off your hands and moves horizontally in the opposite direction at a speed of \( 8.00 \mathrm{~m} / \mathrm{s} \) ?

Step 1
- Mass of person, \( m_1 = 70.0 \, \text{kg} \) - Mass of ball, \( m_2 = 0.400 \, \text{kg} \) - Initial speed of ball, \( v_{2i} = 10.0 \, \text{m/s} \) Show more…

You are standing on a sheet of ice that covers the football stadium parking lot in Buffalo; there is negligible friction between your feet and the ice. A friend throws you a 0.600-kg ball that is traveling horizontally at 10.0 m/s. Your mass is 70.0 kg. (a) If you catch the ball, with what speed do you and the ball move afterward? (b) If the ball hits you and bounces off your chest, so afterward it is moving horizontally at 8.0 m/s in the opposite direction, what is your speed after the collision?

You are standing on a sheet of ice that covers your courtyard; there is negligible friction between your feet and the ice. A friend throws you a $0.400 \mathrm{~kg}$ ball that is traveling horizontally at $10.0 \mathrm{~m} / \mathrm{s}$. Your mass is $70.0 \mathrm{~kg}$. (a) If you catch the ball, with what speed do you and the ball move afterward? (b) If the ball hits you and bounces off your chest, so afterward it is moving horizontally at $7.0 \mathrm{~m} / \mathrm{s}$ in the opposite direction, what is your speed after the collision?
