You're doing this experiment on Mars, where gravity is only 0.38g (where g is Earth's gravity). You take a sample of MXQ1 with a mass of 23 kg, and place it on a flat surface made of MZX2. You give it a horizontal push of 10 N, and it doesn't move. You increase the force to 20 N, and still nothing. 30 N, still nothing. Finally, when you increase the force all the way to 47 N, the sample starts moving. You keep pushing until it reaches a speed of 5.6 m/s, and then you let go. When you let go, it keeps moving, but slows down, and after 3.4 seconds, it comes to a stop a) What is the coefficient of kinetic friction between MXQ1 and MZX2? b) What is the coefficient of static friction between MXQ1 and MZX2?

Komi was on vacation and went to scale Mt. Banahaw. Her weight at the base of the mountain is 540 N; on top she weighs 539.5 N. Note that the gravity acceleration decreases about 0.247 cm/s^2 for each 1000 m ascent. Determine the height in m of point above the base where her weight decreases by 4.912%.
An astronaut is doing a spacewalk on a long tether at 0.1 km away from the International Space Station (mass of 420,000 kg). His spacesuit includes a very sensitive gravitometer, which indicates the gravitational force acting on the astronaut and his spacesuit from the ISS is 7.0 E−7 N. What is the mass of the astronaut in his suit if G = 6.67 E−11 N*m2/kg2? 1. 150 kg 2. 200 kg 3. 250 kg 4. 300 kg

A spring (spring1) of initial length L10 and spring constant kl is hanging down the ceiling, with a ball (ball1) of mass m1 attached to the bottom of the spring. Another spring (spring2) of initial length L 20 and spring constant k2 is hanging down from ball1 with another ball (ball2) of mass m2 attached to the bottom of spring2. Use g to denote gravity, t is time, L1 is the position of ball1 minus the ceiling, L2 is the position of ball2 minus ball1, the velocity of ball1 is v1, and the velocity of ball2 is v2. What is the expression of the net force Fnet1 and Fnet2 acted upon ball1 and ball2?

A "doomsday" asteroid with a mass of 1.0 × 1010 kg is hurtling through space. Unless the asteroid's speed is changed by about 0.25 cm/s, it will collide with Earth and cause tremendous damage. Researchers suggest that a small "space tug" sent to the asteroid's surface could exert a gentle constant force of 2.4 N . For how long must this force act?
A brave but inadequate rugby player is being pushed backward by an opposing player who is exerting a force of 740 N on him. The mass of the losing player plus equipment is 88 kg, and he is accelerating at 1.8 m/s2 backward. Randomized Variables: f = 740 Nm1 = 88 kgm2 = 118 kga = 1.8 m/s2 1. What is the magnitude of the force of friction, in newtons, between the losing player's feet and the grass as he slides backwards? F1 = 2. What is the magnitude of the force, in newtons, that the winning player exerts on the ground to move forward if his mass plus equipment is 118 kg? Assume the second player has the same acceleration as the first. F2=
