PLEASE SHOW WORK. thank you A ball of mass 5kg at the Earth’s surface, and thus subject to a gravitational field, is being pushed up by a force of F = 220N. What is the acceleration of the ball? State both the magnitude and the direction. Take the acceleration of gravity to be g = 9.81m/s2. key: 34.2 m/s2
At the surface of the earth the acceleration due to gravity is 9.8 m/s2. How far above the surface of the earth would the acceleration due to gravity be 10% smaller? In other words, at what height is the acceleration due to gravity 8.82 m/s2?
The force of gravity exerted by Earth on a fully suited astronaut at Earth's surface is 1810 N . What is the magnitude of the gravitational force exerted on her on Jupiter, where the acceleration due to gravity is 25.9 m/s2. What is the magnitude of the gravitational force exerted on her on the Moon, where the acceleration due to gravity is 1.6 m/s2?
An astronaut weighs 850 N on the Earth’s surface. When the astronaut lands on Planet X, she weighs 190 N. To the nearest tenth of a m/s2, what is the acceleration of gravity on Planet X? (hint: first find her mass!) An elevator car loaded with two passengers has a mass of 1200 kg. What tension must be applied by the elevator cable to give the car an acceleration of 1 m/s2 upward? Round your answer to the nearest newton....
What would be the acceleration of gravity (in m/s2) at the surface of a world with six times Earth's mass and nine times its radius? m/s2
A particle falls under gravity from rest through a viscous medium such that the drag force is proportional to the square of the speed. Find the speed () at any time 0 and find the terminal speed v Velocity Forces by Newton's Second Law: dv dt dt ng
My Notes (a) What is the acceleration of gravity, in m/s, on the surface of the Moon? The mass of the moon is 7.35 x 1042 kg and its radius is 1.74 x 106 m. m/s2 (b) What is the acceleration of gravity, in m/s?, on the surface (or outer limit) of Neptune? The mass of Neptune is 1.02 x 10 and its radius is 2.48 x 10 m. kg m/s²

The coefficients of friction between a 1.5 kg block and a surface are μs = 0.50 and μk = 0.40. Assume the only other force acting on the block is that due to gravity. What is the magnitude of the frictional force (in newtons) on the block if the block is moving and the surface is inclined at 30o? Use g = 9.79 m/s2.
The coefficients of friction between a block of mass 1.5 kg and a surface are ?s = 0.60 and ?k = 0.40. Assume the only other force acting on the block is that due to gravity. What is the magnitude of the frictional force (in newtons) on the block if the block is at rest and the surface is inclined at 15o? Use g = 9.79 m/s2.
