I am currently really struggling in my physics class and really need help. I've reached out to both my teacher and school and neither are helping me. My teacher is really hard for me to understand so when learning the material I am left confused. I really do not know how to solve this problem or any problem like this at all. I need as much help as I can get.
A student's car stalls right in front of a speed bump while she is on her way to physics class. To pull it over the bump, she ties a cable to her bumper and to a nearby tree, and pulls with a force, F, of 81.0 lbs (360 N) at the midpoint in a perpendicular direction.If θ is 11.0°, what is the size of the force pulling the car in lbs

- A box of mass 3.0 kg slides down a rough vertical wall. The gravitational force on the box is 29.4 N . When the box reaches a speed of 2.5 m/s , you start pushing on one edge of the box at a 45∘∘ angle (use degrees in your calculations throughout this problem) with a constant force of magnitude FpFpF_p = 23.0 N , as shown in (Figure 1). There is now a frictional force between the box and the wall of magnitude 13.0 N . How fast is the box sliding 2.6 s after you started pushing on it?arrow_forwardJeremy, an astronaut employed by SpaceX, fully suited, weighs 2.1 x 10° N on Earth. He is about to jump down from a space capsule that has just safely landed on exoplanet K2-18b. The drop to the surface of K2-18b was determined to be 3.7 m, and Jeremy's gravitational potential energy relative to the surface is 1.6 x 103 J. What is the gravitational field strength on exoplanet K2-18b? 2.6 N/kg 2.0 N/kg Option 4 Option 1 2.2 N/kg 2.4 N/kg Option 2 Option 3arrow_forwardThe passengers lie back on pads which line the interior of the chamber. These are all inclined at 62° to the horizontal. Each pad is mounted on a small track on the Gravitron wall. wall track pad 62° floor As the Gravitron rotates faster and faster, a speed is reached where each pad rises up its track so that the passengers lose contact with the floor of the chamber. If the mass of a passenger is 80 kg, the normal contact force on the passenger is:arrow_forward
- A dancer is standing on one leg on a drawbridge that is about to open. The coefficients of static and kinetic friction between the drawbridge and the dancer's foot are μs and μk, respectively. n⃗ represents the normal force exerted on the dancer by the bridge, and F⃗g represents the gravitational force exerted on the dancer, as shown in the drawing.(Figure 1). For all the questions, we can assume that the bridge is a perfectly flat surface and lacks the curvature characteristic of most bridges. Before the drawbridge starts to open, it is perfectly level with the ground. The dancer is standing still on one leg. What is the horizontal component of the friction force f⃗? (Express your answer in terms of some or all of the variables n, μs, and/or μk.) (Figure 2). The drawbridge then starts to rise. The dancer continues to stand on one leg. The drawbridge stops just at the point where the dancer is on the verge of slipping. What is the magnitude f of the frictional force now? (Express…arrow_forwardThe center of a moon of mass m = 8 × 1023 kg is a distance D = 97 × 105 km from the center of a planet of mass M = 10.9 × 1025 kg. At some distance x from the center of the planet, along a line connecting the centers of planet and moon, the net force on an object will be zero. a. Derive an expression for x. b. Calculate x in kilometers, given the variables in the beginning of the problem.arrow_forwardOver the holiday break you have an internship with an ice skating show. An ice skater will start from rest and slide down an ice-covered ramp. At the bottom of the ramp, the skater will glide around an ice-covered loop which is the inside of a vertical circle before emerging out onto the skating rink floor. For a spectacular effect, the circular loop will have a diameter of 30 feet. Your task is to determine the minimum height from the rink floor to the top of the ramp for the skater to make it around the loop. When barely making it around, the skater briefly loses contact with the ice at the top of the loop.arrow_forward
- In deep space, an astronaut is whipping a heavy tool around in a circle by a taut cable. The cable is 1 meter long (from the astronaut's fist to the tool), and the tool makes a full trip around the circle in half a second as it moves with constant speed. The mass of the tool is 10 kg. What is the tension in the cable?arrow_forwardAt an amusement park there is a ride in which cylindrically shaped chambers spin around a central axis. People sit in seats facing the axis, their backs against the outer wall. At one instant the outer wall moves at a speed of 3.16 m/s, and an 85.3-kg person feels a 546-N force pressing against his back. What is the radius of a chamber?arrow_forwardThe mass of a roller-coaster car, including its passengers, is 500 kg. Its speed at the bottom of the track in Figure P6.16 is 19 m/s. The radius of this section of the track is r1 = 25 m. Find the force that a seat in the roller-coaster car exerts on a 50-kg passenger at the lowest point.arrow_forward

As you swing the tennis ball, the force of tension in the cord keeps the tennis ball in a circular path. The mass of the tennis ball is 0.25 kg, and as it swings around, speed of the tennis ball is 3.8 m/s. What is the force of tension in the cord? (the unit of force is the 'Newton' )arrow_forwardA team of astronauts is on a mission to land on and explore a large asteroid. In addition to collecting samples and performing experiments, one of their tasks is to demonstrate the concept of the escape speed by throwing rocks straight up at various initial speeds. With what minimum initial speed ?escvesc will the rocks need to be thrown in order for them never to "fall" back to the asteroid? Assume that the asteroid is approximately spherical, with an average density ?=4.10×106 g/m3ρ=4.10×106 g/m3 and volume ?=1.25×1012 m3V=1.25×1012 m3 .
