A space-walking astronaut of total mass 148 kg exerts a force of 265 N on a free-floating satellite of mass 635 kg, pushing it in the positive x- direction. (a) What is the reaction force exerted by the satellite on the astronaut? Calculate the accelerations of (b) the astronaut, .and (c) the satellite

A 975-kg jeep comes to rest from a speed of 97.5 km/h in a distance of 105 m. Consider that the jeep is initially traveling in the positive direction. If the brakes are applied consistently and are the only thing making the jeep come to a stop, calculate the force (in newtons, in a component along the direction of motion of the jeep) that the brakes apply on the jeep. Suppose instead of braking that the jeep hits a concrete abutment at full speed and is brought to a stop in 2.00 m. Calculate the force, in newtons, exerted on the jeep in this case. What is the ratio of the force on the jeep from the concrete to the braking force?

Two skaters, a man and a woman, are standing on ice. Neglect any friction between the skate blades and the ice. The mass of the man is 79 kg, and the mass of the woman is 54 kg. The woman pushes on the man with a force of 58 N due east. Determine the acceleration (magnitude and direction) of (a) the man and (b) the woman. (a) aman (b) awom 0.73 i -1.1 eTextbook and Media m/s^2 v m/s^2 v due east due west

A block with a carpeted underside (mass of .122 kg) is pulled by a wheeled cart (mass of .453 kg) attached by a piece of cordage down a ramp with an angle measured to be 3.9 degrees. The block and cart travel a distance of .7535 meters in 4.61 seconds. If the block and cart move together simultaneously, determine the acceleration (acceleration is constant) and then determine the static coefficient and kinetic coefficient. 122 kg 453 kg 3.9°(

A 2.9 kg mass is initially at rest while upon a horizontal surface. An applied force of 16 N is exerted on the mass at an angle of -25 degrees with respect to the +x direction. If the coefficient of kinetic friction is 0.244 what is the magnitude of the acceleration produced?

Consider a conical pendulum with a bob of mass m = 86.0 kg on a string of length L = 10.0 m that makes an angle of 0 = 6.00° with the vertical. (Consider +î to be towards the center of the circular path and +j to be upward.) (a) Determine the horizontal and vertical components of the force exerted by the string on the pendulum. Draw a free-body diagram of the bob when the string lies in the plane of the page and draw the forces that act on the bob. N î + 843.66 N ĵ (b) Determine the radial acceleration of the bob. m/s2

In a soccer match against Mexico in 2014, US Women’s National Team striker Alex Morgan scored a sweetheaded goal in the 79th minute of the game. Just as the ball left her head, the horizontal component of its acceleration was 225 m/s , and the vertical component of its acceleration was -200 m/s (assuming thepositive direction points up). If the ball has a mass of 425 g, what was the magnitude and direction of theforce she applied to the ball? Note- you can ignore the weight of the ball.

An astronaut on the moon places a package on a scale and finds its weight to be 35 N. (a) What would the weight of the package be on the earth?                      N(b) What is the mass of the package on the moon?                      kg(c) What is the package's mass on earth?                       kg

The rocket sled shown in the figure decelerates at a rate of 155 m/s2 . Its passenger has a mass of 75 kg. Use a coordinate system in which the sled is moving in the positive direction, and assume the contact forces with the seat are the only forces acting on the passenger.(a)  Calculate the horizontal component of the force that the seat exerts against his body, in newtons. What is the ratio of the magnitude of the horizontal force to the magnitude of the force of gravity? Find the angle of the total force that the seat exerts against his body. Give your answer in degrees from the negative horizontal direction, with positive being clockwise.

The nucleus of Be, which consists of 4 protons and 4 neutrons, is very unstable and spontaneously breaks into two alpha particles (helium nuclei, each consisting of 2 protons and 2 neutrons). (a) What is the force between the two alpha particles when they are 3.00 x 10-15 m apart? N (b) What is the initial magnitude of the acceleration of the alpha particles due to this force? Note that the mass of an alpha particle is 4.0026 u. m/s²
