3) A mass of 5 kg is resting on a horizontal, frictionless surface. Force 1 is applied to it at 20 degrees below the horizontal in the -x direction, force 2 has a magnitude of 88 N and is applied in the +x direction , and force 3 has a magnitude of 25 N and is applied vertically downwards. When these forces are applied, the normal force acting on the mass is twice the amount of its weight. Also, when...

An object with a mass of 5 kg lies is on a horizontal surface with a coefficient of kinetic friction of 0.75. A force of 30 Nis applied to it DOWNWARDS, perpendicular to the surface, a force of 40 N is applied to it at an angle of 30 degrees above the +x axis, and a force of 20 N is applied to it in the negative x direction. The mass moves 10 m in the positive x direction with...

1 2 A projectile PA is launched from point A towards the east with an initial launch velocity ves and an initial launch angle of 8aA. The impact point of the projectile Pa is a point B in a valley with an ordinate, you, located below the elevation of point A. The launch from point A is instantaneously detected at point B, and a counter projectile Pa ts launched simultaneously towards the west to intercept the incoming projectile PA. Projectile...

A 6.00-kg ornament is held at rest by two light wires that form 30° angles with the vertical, as shown in the figure. An external force of magnitude F acts vertically downward on the ornament. The tension exerted by each of the two wires is denoted by T. A free-body diagram, showing the four forces that act on the box, is shown in the figure. If the magnitude of force F is 410 N, what is the magnitude of the...

A circus act consists of a performer (a "human cannonball") being launched from a cannon into a net at the other end of the stage. The performer (mass 60 kg) leaves the cannon at a speed of 25 m/s at an angle of 30o above horizontal. She comes out of the cannon at a height of 2 meters above the ground and lands in the net at a horizontal distance of 45 meters away from the launch point. Let +x...
