A mass (m) moves along the x-axis in thepositive direction with a constant speed vo. Att=0, the mass passes through the origin and issubject to the force F = -Fo(x/H)e^(-x/H) for x>0. Fo and H are both positive constants.%3Da. Calculate the minimum initial speed requiredfor the mass to pass through the origin andnever turn back in terms of the constants m, Fo,and H.b. Write the velocity of m in unit vector notation,long after it crosses the origin (t>>0) and in thethe case of vo>v0min where vomin is the resultin part a.

Ignore air resistance. A person with a mass of 60.0kg does a "bungee jump" from a bridge. They fall a distance of 6.31m before the bungee cord (which acts like a vertical spring) starts to pull up on them. After this moment, the person moves downward another 12.6m before reaching their lowest point. N The spring constant of the bungee cord is. m BIZ
A football punter accelerates a football from rest to a speed of 15 m/s during the time in which his toe is in contact with the ball (about 0.28 s). If the football has a mass of 0.43 kg, what average force does the punter exert on the ball? N
Komila knows that an egg breaks if it falls onto a concrete floor from a height of 0.4 mm. She finds, however, that an egg does not break when it falls from the same height onto a floor that is covered with a 2.0-cmcm-thick carpet. Part C Determine the minimum carpet thickness to prevent an egg from breaking after a drop from a height of 1.0 mm. Assume that the carpets exert the same constant force on the egg.

E The ship was traveling at 2.5 m/s toward the reef when a mechanical failure caused the rudder to jam in the straight-ahead position. At that point in time, the ship was 900 m from the reef. The wind was blowing directly toward the reef and exerting a constant force of 9.00 x 10' N on the boat in a direction toward the reef. The mass of the ship and its cargo was 5.50 x 10' kg. During the preparation for the trial, the captain claims that without control of the direction of travel, the only choice he had was to put the engines in reverse at maximum power, such that the total force exerted by the frictional drag force of the water on the propeller was 1.25 x 10 N in a direction away trom the reef. From this information, construct a convincing argument that nothing the captain could do in this situation could have prevented the ship from striking the reef.
Suppose a car approaches a hill and has an initial speed of 120 km/h at the bottom of the hill. The driver takes her foot off of the gas pedal and allows the car to coast up the hill. Note: the 790-kg car with an initial speed of 120 km/h is observed to coast up a hill and stops at a height 21 m above its starting point. a.) What is the magnitude of the average force of friction, in newtons, if the hill has a slope 2.7° above the horizontal?
