Why doesn’t a heavy object accelerate more than a light object when both are freely falling?
Step by step
Solved in 2 steps
- A rocket becomes progressively easier to accelerate as it travels through space. Why is this so? (Hint: About 90% of the mass of a newly launched rocket is fuel.)Do heavier objects fall more slowly than lighter objects ? Why??Calculate the force required to accelerate an electron from a speed of 100 m/s to 100 km/s in the same direction in a distance of 5.0 cm. The mass of an electron is 9.1x10-31 kg.
- If I'm on an elevator that breaks free and falls down the shaft, can I jump at the last second to avoid getting hurt?Can I prevent injury by leaping at the last second if I'm on an elevator that breaks free and plummets down the shaft?A heavy crate accidentally falls from a high-flying airplane just as it flies directly above a shiny red Porsche smartly parked in a car lot. Relative to the Porsche, where will the crate crash?
- The force of gravity on a 6-kg mass is a half as strong as the force of gravity on a 3-kg mass b exactly as strong as the force of gravity on a 3-kg mass c twice as strong as the force of gravity on a 3-kg massLara claims that if an object is accelerating, it must be moving. She also claims that if an object is not accelerating, it must be at rest. Do you agree with Lara? If not, what would you say to her to convince her she’s wrong?A bullet fired from a rifle begins to fall(a) as soon as it leaves the barrel.(b) after air friction reduces its speed.(c) not at all if air resistance is ignored.
- Which allows you to jump the farthest? Why? Only using your ankles? Knees and ankles? Hips Knees ankles?If the net force on a 10 kg object is 40 N, what can we say about this object? The object will be accelerating at 4 m/s/s The object will have a velocity of 400 m/s The object will have a speed of 4 m/s The object will have a velocity of 4 m/sHow much does an astronaut with a mass of 100kg weigh way out in space, far far away from any planets, suns, moons (any masses)?
