Please help! I'm stuck.

1. The International Space Station is in orbit at 405.62 km above the Earth's Surface. Solve for the velocity and acceleration. 2. A satellite is placed in orbit 380 km above the moon for a future Orion mission. What is its velocity and acceleration? 3. A 2300 kg truck is going around a 73m radius turn at 16 m/s. Solve for the centripetal force and angular velocity. 4. A satellite is at the end of its serviceable life and is moved to a graveyard orbit of 51040kg from the earth's surface. Solve for acceleration, gravity, and velocity. 5. A satellite is in Earth orbit at an altitude of 445 km. Solve for the acceleration, velocity, and gravity. 6. A 1762 kg car rounds a curve at 20.5 m/s. The curve radius is 87 meters. If the coefficient of friction between the tires and road is 0.93, will the car successfully round this curve
