اتمنى منكم مساعدتي في حل هذه المسائل المهمه في اختباري يوم السبت القادم

Q1 - force Fx= ct where c is positive constants .The force acts on a paricle of maas m which starts rest and t=0 and at X=Xo faind

a) Tha velocity Vx as functions of the time t

b) the position x as functions of the time t

.................................................. .................................................. .............................
Q2- A particle moves on tge x-axis . The force on it is given by
Fx=kx , where k is apositive constants

a) calculate the work w done by the force on the particle if displaced from x=0 to any point x

b) what is the potential energy function Vx . Take V=0 at X=0

c) If the particle starts from the rest at x=b . what is the speed of the particle at x=2 b ? X
