A person reaches a maximum height of 58 cm when jumping straight up from a crouched position. During the jump itself, the person's body from the knees up rises a distance of around 41 cm. To keep the calculations simple and yet get a reasonable result, assume that the entire body rises this much during the jump. Initial velocity of jump is 3.4 m/s. In terms of this jumper's weight W , what force does the ground exert on him...

4. An air plane flies horizontally with X-velocity  V0x= 360 m/s at an altitude (height above the ground)=H=Dy= 3645 m. A bag of mass M=40 Kg falls off from the plane, and moves to the ground in a parabolic path without air resistance while the plane ciontinues to fly horizontally. Use g=10 m/s2 and V0Y=0       Part A The time the bag takes to hit the ground is t=____ seconds The time the bag takes to hit the ground is t=____...

You throw a ball vertically upward with an initial velocity of 10 m/s from a window located 20 m above the ground. Knowing that the acceleration of the ball is constant and equal to 9.81 m/s^2 downward (this makes for negative acceleration as upward motion is positive and downward motion is negative and gravity pulls downward), determine: (a) The acceleration at t = 2 s (b) The equation for velocity (Because you are looking for an equation for velocity, you...
