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

Problem 18: An electrically charged base ball of mass 150g travels with a constant velocity of 89.5mph on a horizontal straight line in a southwestern direction, suspended against gravity by the magnetic force due to the earth's magnetic field. The earth's B-field is pointing straight north, horizontally, with a strength of 60 T. The earth's gravitational acceleration is 9.81m/s2 and 1mile = 1,609m. Neglect air resistance. Find y, the electric charge (amount and sign!). carried by the ball. Hints: (1)...

Question 3 5 pts You are using a sanding block to smooth your ceiling before painting. The box has a mass M=0.67 kg and is held up against and pushed across the ceiling. You are pushing the block with a force of magnitude 9.74 N. This force is at an angle 20.3 degrees from the vertical (+y) direction, this being the angle between the force and the y- axis. The coefficient of kinetic friction between...
