Engineering Mechanics - Dynamics Chapter 13 Problem 13-38 An electron of mass m is discharged with an initial horizontal velocity of v 0 . If it is subjected to two fields of force for which F x = F 0 and F y = 0.3 F 0 where F 0 is constant, determine the equation of the path, and the speed of the electron at any time t . Solution: F 0 ma x = 0.3 F 0 y = a x F 0 m = a y 0.3 F 0 m = v x F 0 m tv 0 + = v y 0.3 F 0 m t = s x F 0 m t 2 2 v 0 t + = s y 0.3 F 0 m t 2 2 = t 20 s y m 3 F 0 = Thus s x 10 s y 3 v 0 20 s y m 3 F 0 + = vv x 2 v y 2 + = v F 0 m 0 + 2 0.3 F 0 m t 2 + = *Problem 13-39 The conveyor belt delivers each crate of mass
