1- A particle moves along the x axis. Its position varies with time according to the expression x(t)=-4t+2t² m. Determine the displacement and average velocity of the particle in the time interval t=0 s to t = 1 s and from t = 1 stot = 3 s 2- The velocity of a particle moving along the x-axis varies in time according to the expression: Vx=40-5t-m/s (a) Find the average acceleration in the time interval t=0 s to t = 2 s. (b) Determine the acceleration at t = 2 s. 3- A jet lands on the aircraft carrier at 63 m/s. What is its acceleration if it stops in 2 s? 4- Find the required time for a car to move 98 m if it starts from rest and acceleration at 40 m/s²? 5- A rock of mass 5 kg falls with an acceleration of 9.8 m/s2. What is the magnitude of the force acting on the rock? 6- A car with mass 2000 kg moves with velocity 20 m/s on a friction surface. If the car takes 100 m to stop, determine the friction force. 1- A particle moves along the x axis. Its position varies with time according to the expression x(t)=-4t+2t² m.
