- 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?During 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? What is the minimum stopping distance?A moving cart of mass 3.5 kg crashes into a stationary cart of mass 10.5 kg as shown. The carts are prevented from touching one another during the collision by a pair of neodymium magnets mounted on the ends of the carts and positioned for repulsion. After separating, the more massive cart moves to the right at 1.4 m/s. What are the final speed and direction of motion of the less massive cart? strong magnets Vfi VGi = 0 3.5 kg 10.5 kg Frictionless surface
- A 1150 kg car drives along a city street at 20.0miles per hour (8.94 m/s). What speed must the 0.142 baseball have if its momentum is to be equal in magnitude to that of the car?An astronaut of mass 65.0 kg is at rest relative to her space vehicle with nothing behind her except the empty,dark, vacuum of space. Another astronaut decides to play a practical joke on her and throws a 10.0 kg anvil(because those are totally used in space) at her with a velocity of 3.00 m/s. How fast do she and the anvil moveonce she catches it? Just to lower your anxiety, there is a way for her to get back to the space vehicleA man holding a rock sits on a sled that is sliding across a frozen lake (negligible friction) with a speed of 0.490 m/s. 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/s
