    Starting from rest, a 68.0 kg woman jumps down to the floor from a height of 0.790 m, and immediately jumps back up into the air. While she is in contact with the ground during the time interval 0 < t < 0.800 s, the force she exerts on the floor can be modeled using the function F = 9,200t − 11,500t2 where F is in newtons and t is in seconds. (a) What impulse (in N · s) did...

  • A point mass of m = 3 kg is currently moving on a frictionless ground into

    A point mass of m = 3 kg is currently moving on a frictionless ground into the positive x-direction with constant speed vo =7 [m/s]. In an x-interval of 2 [m] lies ahead, there will be a chance to apply constant force (over the interval) on the mass to change its direction so that it will be launched with an angle of 45e to the ground after passing the interval. i. If the force can only be in the y-direction, what...

    While unrealistic, we will examine the forces on a leg when one falls from a height by approximating the leg as a uniform cylinder of bone with a diameter of 2.3 cm and ignoring any shear forces. Human bone can be compressed with approximately 1.7 × 108 N/m2 before breaking. A man with a mass of 70 kg falls from a height of 7 m. Assume his acceleration once he hits the ground is constant. For these calculations, g =...

    QUESTION 1 Two skaters, one of mass 80 kg, the other of mass 40 kg, are standing next to each other on frictionless ice rink. The 40 kg skater pushes the 80 kg skater. After the push, the 80 kg skater is going at 1 m/s. How fast and in what direction is the 40 kg skater going after the push? (HINT: use the fact that since there are no external forces, the velocity of the center of mass of...
