Homework Statement
An electron of mass 9.11 multiplied by 10^-31 kg has an initial speed of 4.00 multiplied by 10^5 m/s. It travels in a straight line, and its speed increases to 7.00 multiplied by 10^5 m/s in a distance of 5.00 cm.
(a) Assuming its acceleration is constant, determine the...
Homework Statement
A force F applied to an object of mass m1 produces an acceleration of 3.00 m/s2. The same force applied to a second object of mass m2 produces an acceleration of 1.30 m/s2.
Find the ration of m1/m2
If m1 and m2 are combined, find their acceleration under the action of...
wow nevermind solved it...
found Fn first using the N of the crate and sin of the applied force, then i plugged that into
ma=uFn and found m by dividing 880 by 9.8 then just solved for a
Homework Statement
A 880 N crate is being pulled across a level floor by a force F of 395 N at an angle of 25° above the horizontal. The coefficient of kinetic friction between the crate and the floor is 0.25. Find the magnitude of the acceleration of the crate.
