Hi, I need detailed answers to these questions to assessment:

1. Ms. Mercury pushes a 25 kg buffing machine forward with a force of 30 lbs [Forward 20o Down]. The coefficient of friction is 0.275. Determine time it takes to reach the desired speed of 1.5 m/s from rest.

2. Ms. Venus pulls a sleigh massing 1 tonne with 220 lbs [East 30o Up]. Ms. Luna helps her out by pushing with 165 lbs [East 10o Down]. Determine the coefficient of friction if they maintain a uniform velocity of 1.5 m/s.

3. Dr. Mars has a mass of 75 kg and weighs 735 N or 165 lbs on the Earth. a) What is his weight in N and lbs on Jupiter where the acceleration due to gravity is 24.8 m/s2? b) If he weighs 63.1 lbs on the planet Martes then determine the gravitational force field strength on Martes.

4. Mr. Neptune picks up his ballet dance partner Ms. Pluto who masses 45 kg and overcoming gravity tosses her upwards and forwards with an average applied force of 220 lbs [Fwd 60o Up] for 0.500 s. Gravity is acting on Ms. Pluto as well. Determine her final velocity and then determine how far away she will land if he releases her from a height of 2m.

5. Ms. Saturn compresses a spring 80 cm using 200 lbs of force. Determine the spring constant (stiffness) in N/m. She then uses the spring in a cylinder it to fire a 150 g baseball with a launch angle of [East 45o Up] from an initial height of 1.5 m. Determine the how far away the baseball will land from her if she compressed the launcher 50 cm and the average internal friction force of the launcher is 6.818 N.
