Question

A F-35 stealth fighter jet traveling at a constant speed of 1.20 x 102 m/s executes a vertical loop with a radius of 5.00 x 10²m. If the mass of the pilot is 70.0 kg, the magnitude of the force exerted on the pilot by the seat at the bottom of the loop is

4. A uniform ladder 10.0 m long and weighing 50.0 N rests against a smooth wall (Note: a smooth wall means that there is no frictional force between the ladder and the wall), as shown in the figure below. If the coefficient of static friction between the ladder and the ground is 0.360 and the ladder makes a 60.0° angle with respect to the horizontal, how far along the length of the ladder can a 70.0-kg painter climb before the ladder starts to slip? (a) 6.33 m (b) 5.24 m (c) 2.78 m (d) 4.99 m SMOOTH WALL ( Hs =0) ladday 60.0° (GROUND (=0. 360) 5. At what maximum speed can a car manage a turn on a wet, level road with coefficient of static friction 0.230 without sliding out of control? The radius of the turn is 25.0 m. (a) 11.8 m/s (b) 7.51 m/s (c) 5.67 m/s (d) 8.90 m/s 6. An ice skater is able to make a triple-spins in the air before landing on the ice field safely is because of the following physical law: (a) Conservation of mechanical energy (b) Conservation of kinetic energy (c) Conservation of linear momentum (d) None of the above 7. AF-35 stealth fighter jet traveling at a constant speed of 1.20 x 102 m/s executes a vertical loop with a radius of 5.00 x 10² m. If the mass of the pilot is 70.0 kg, the magnitude of the force exerted on the pilot by the seat at the bottom of the loop is (a) 2.70 x 103 N (b) 5.45 x 102 N (c) 1.89 x 104 N (d) 3.14 x 10' N
