- an iron ball with a mass of 67.5 kg is traveling with an initial velocity of 20.5 m/s. the ball is hit with a hammer, which remains in contact with the ball for 0.20 sec. how much force must the hammer hit the ball with to cause it to change directions?arrow_forwardDuring a car collision, the knee, thighbone, and hip can sustain a force no greater than 4000 NN. Forces that exceed this amount could cause dislocations or fractures. Assume that in a collision a knee stops when it hits the car's dashboard. Also assume that the mass of the body parts stopped by the knee is about 20% of the total body mass. The person with a mass of 90 kgkg is initially traveling at 18 m/sm/s (40 mi/hmi/h). What minimum stopping time interval in needed to avoid injury to the knee?

The total mass of the sled, man, and rock is 94.0 kg. The mass of the rock is 0.270 kg and the man can throw it with a speed of 15.5 m/s. Both speeds are relative to the ground. Determine the speed of the sled (in m/s) if the man throws the rock forward (i.e., in the direction the sled is moving). m/s Determine the speed of the sled (in m/s) if the man throws the rock directly backward. m/sarrow_forward
