The force that is pushing the crate up the ramp is competing with at least another two forces, those being G force= defines the attraction to the earth and Ff, the friction between the crate and the rough material of the ramp
Any Force can be defined by the weigh of a particular body and the acceleration
the kinetic friction indicative would be defined by the report between the active force and the friction force, considering G
So 5000-22%×5000=250× a
a=3900/250 m/s
Answer:
A to B is in constant speed. b to c is speeding up. c to d is not moving. d to e is slowing down.
Explanation:
a to b is at a constant rate of acceleration. (It is speed up but it is doing it consistantly) The line is curving upwards means it is speeding up just not consistantly like a to b. c to d is not going up or down which means it is not in motion. d to e is slowing down because the line curvs down ward.
Fusion is a more controlled and les violent alternative to nuclear fission. although both can be catastrophic if a melt down occurs.
