A bat strikes a 0.145 kg baseball. Just before impact, the ball is traveling horizontally to the right at 50.0 m/s; when it leaves the bat, the ball is traveling to the left at an angle of 30° above horizontal with a speed of 52.0 m/s. The ball and bat are in contact for 1.75 ms. Find the z- and y-components of the average force on the ball. Suppose that the +z axis is directed to the right, and the +y axis is directed upward. Express your answers in newtons using three significant figures separated by a comma. F₂. Fy= 96 IVE| ΑΣΦ 4 ? N

An incoming tennis ball (mass 0.060 kg) has a speed of 14 m/s. The player hits the ball with a racquet, giving the ball a speed of 30 m/s in the opposite direction. If the contact time is 0.005 s, what is the average force of the racquet on the ball?

An interacting system of two objects has no external force acting on the system. The firstobject has a mass 2.00 kg and is moving with a velocity (2.00 m/s)i + (1.00 m/s)j at time t =0.00 s. The second object has a mass 3.00 kg and is moving with a velocity (-1.00 m/s)i +(1.00 m/s)j at time t = 0.00 s. The second object is moving with a velocity (2.00 m/s)i +(-1.00 m/s)j at time t = 1.00 s.  What is the total momentum of the system at time t = 0.00 s?

Problem 23:  Three beads are placed on the vertices of an equilateral triangle of side d = 4.1 cm. The first bead of mass m1 = 135 g is placed on the top vertex. The second bead of mass m2= 55 g is placed on the left vertex. The third bead of mass m3 = 85 g is placed on the right vertex.  Part (a)  Write a symbolic equation for the horizontal component of the center of mass relative to the left vertex of the triangle.   Part (c)  Write a symbolic equation for the vertical component of the center of mass relative to the base of the triangle.
