Determine the resultant of the following: 9.0 N at 40°, 8.0 N at 120°, and 14.0 N at 22 0°, all
angles being measured with the positive x-axis. Use component method in finding the resultant.
what is the angular velocity of an object traveling in a circle of radius 0.75 m with a linear speed of 3.5 m/s ?
A block slides from rest from the top of an inclined plane 10 m long which is inclined 37° with
the horizontal. If the coefficient of kinetic friction is 0.30, determine how long it will take the
block to reach the bottom of the plane.
A 4.25 kg block rest on a horizontal tabletop. A cord is attached to this block, the cord passing
over a pulley at the edge of the table. At the end of the cord is hung another block weighing 7
kg. Determine the tension in the cord.
A curve along the barangay is to be designed for motorela moving at 30 kilometers per hour. Find
the angle of banking if the radius of the curve is 20 m.
A stone fall from a railroad overpass which is 36m high into the path of a train which is
approaching the overpass with uniform speed. If the stone falls when the train is 50m away from
the overpass and the stone hits the ground just as the train arrives at that spot, how fast is the
train (in kilometer per hour) moving?
Determine the resultant of the following: 9.0 N at 40°, 8.0 N at 120°, and 14.0 N at 22 0°, all
angles being measured with the positive x-axis. Use component method in finding the resultant.
A ball of mass 1000kg is dropped from a height of 5m and rebounded to a height of 25cm calculate:(I) it's kinetic energy just before impact (ii) its initial rebounce velocity and kinetic energy
What change in velocity would be produced on a body of mass 4kg if a constant force of 16N acts on it for 2s
A Boy applied a force of 20N at an angle of 60 to the horizontal in order to move a load. Through a horizontal distance of 10m. Calculate the work by the day.
