- As shown in the figure below, we have a square one meter on a side that is free to rotate about an axis perpendicular to the plane of the square, a distance a from one side and a distance b from the other side. a = b = b (i) Two forces, and F2, are applied to diagonally opposite corners, and act along the sides of the square, first as shown in case (i) and then as shown in case (ii) of the drawing. In each case the net torque produced by the forces is zero. If the magnitude of F2 is 4 times that of F₁, find the distances a and b that locate the axis. It should be noted that a and b are not drawn to scale. m m b aA ball of mass 5.5 kg is released from rest from the top of a 4.0 m long hill that is inclined at 30°, as shown in figure. The ball rolls along the hill without slipping. The rotational inertia of a sphere of mass M and radius R about its center of mass is MR. (cos 30° = 0.866, sin 30° = 0.5, g = 9.8m/s?) a) Calculate the force due to friction acting on the ball as it rolls along the hill, b) Calculate the linear speed of the center of mass of the ball when it reaches the bottom edge of the hill, c) A wagon containing a box is at rest on the ground below the hill so that the ball falls the vertical distance of 3.0 m and lands and sticks in the center of the box. The total mass of the wagon and the box is 12 kg. Calculate the horizontal speed of the wagon immediately after the ball lands in it. 4,0 m 3.0 mA bullet is fired at an angle of 60° to the horizontal with an inital velocity of 200m/s.
