Report
In this week's physics simulation experiment, if the cart's mass is increased, how does the acceleration of the cart change? Decreases A deep space probe is launched and at 10,000 miles from Earth's center, experiences a gravitational force of 359 lbs. What is the gravitational force on the the probe at a distance of 20,000 miles? 89.75 A spring stretches 0.25 m from rest when a mass of 1 kg is placed on the spring. What is the spring constant k for the spring (in units of N/m)? 39.24 A centripetal force of 1000 N acts on a 4,246 kg satellite moving with a speed of 8000 m/s in a circular orbit around a planet. What is the radius of its orbit? 271,840 An object with a mass of [m] kg is in free fall in a vacuum tube (negligible air resistance) with an acceleration of 9.81 m/s². What will be the object's acceleration if its mass is doubled? 9.81 m/s^2 A jet accelerates from rest at 2 m/s². How far does the jet travel during 5 seconds? 25 An aircraft carrier catapult accelerates a 18,635 kg jet from rest to 90 m/s in 3 sec. What force does the catapult exert on the jet? 559,050 An airplane can withstand a maximum acceleration of 5 g's. If the airplane's mass is
1,623 kg, what magnitude of force (in Newtons) will cause this acceleration? 79,538 An airliner has a weight of 387,585 lbs. What is its weight in Newtons? 1,724,997 In an experiment performed on the International Space Station, a force of 47 Newtons causes an object to have an acceleration of 2 m/s². What is the object's mass? 23.5
