to be honest its the whole scientific notation thing that's throwing me off lol

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...

ah stupid mistake on my part, got any ideas on the second part?

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. Homework Equations not...
