A super-bouncy-ball with a mass of 0.5 kg is thrown at a wall with a velocity of 5 m/s and it bounces
back with a velocity of -5 m/s. A no-bounce-ball of the same mass is thrown at a wall at the same
velocity and does not bounce back at all. Which ball experiences a greater change in momentum?
O A the super-bouncy-ball
the no-bounce-ball
o they would have the same change in momentum

Ahole in the ground in the shape of an inverted cone is 14 meters deep and has radius at the top of 11 meters. the cone is filled to the top with sawdust. the density of the sawdust depends upon the depth, x, following the formula ρ ( x ) = 2.5 + 1.2 e − 0.7 x kg/m3. find the total mass of sawdust in the conical hole.
