1. Student Anatoli want to move to Natyad school He gets Nafyad school students bus which is moving the rate of in second from rest . The students bus moves at this velocity for 40 seconds However the students bus slow down and come to stop in 10 seconds It is at rest for 20 seconds It moves at 10 for seconds and then slowdown to come to in far 10 seconds Whear as student to li leave the school student bus
A. Draw the velocity time graph to show the travel the student school bus ?
B. At what interval of time , the acceleration of the student School bus more accelerates ?
C. How far does student Anatoli move on the school bus ?

2. A block of Weight 100N suspended from three strings of the ropes make angles of theta_{1} = 60 deg and theta_{2} = 30 deg with the horisontal If the system is in equilibrium ,
A. show the figure of the given problem.
B. determine the tensions and in the string 3

3. if the results of (A + B) is three times of ( A -B) and the Vectors have the same results. The angle between vectors will be

4) If a particle travelling at initial Velocity of 21 m/s from at t = 0 second Under the action of force and a particles accelerates at constant acceleration ( 4i +3j ) m with 42 m along k axis What is the axis of the particle at the instant?​
