You hang a 1.0 kg mass from a spring scale. But this time, instead of holding your hand still so that the acceleration is zero, you let your arm drop so that the mass accelerates downward at 5.2 m/s2. What force (how many Newtons) will the spring scale read while this acceleration is happening assuming that you are standing on the surface of Earth, so that the force on the 1.0 kg mass due to gravity is 9.8 Newtons?

On Earth, a squash weighs 5kg. An astronaut transports it into space on its way to Mars, where the acceleration due to gravity is at 3.7 m/s2. Which of the following statements is correct? a. The squash's mass and weight on Mars' surface are 5kg and 49N, respectively. b. The squash's mass and weight on Mars' surface are 5kg and 18.5N, respectively. c. The squash's mass and weight on Mars' surface are 18.5N and 5kg, respectively. d. The squash's mass and weight on Mars' surface are 49N and 18.5N, respectively.

Consider a human who weighs 862 N on Earth. What is the person's mass on Earth? And what is the same person's mass on Mars, where the acceleration due to gravity is 3.7 m/s2?

Weight refers to the force of gravity acting on a mass. We often calculate the weight of an object by multiplying its mass by the local acceleration due to gravity. The value of gravitational acceleration on the surface of Mars is 0.38 times that on Earth. Assume your mass is 81.00 kg. Then your weight on Earth is 793.80 newtons (793.80 N = m × g = 81.00 kg × 9.8 m/s2). What would be your mass on Mars? kg What would be your weight on Mars? N

You are standing on a bathroom scale in an elevator in a tall buildingg Your mass is m=70 kg. The elevator starts from rest and travels with a velocity that varies with time according to = (t+0.05 ) (m/s). What is the reading of the bathroom scale at time t = 4s? %3D (g=-gj and the magnitude of the gravitational acceleration is g = 10 m/s)

The gravitational force between two people is found to be 5.9 x 10-11 N. What would the gravitational force be between the two people if person A's mass is decreased to 1/3 the original value, person B's mass is increased to 3/2 of the original mass, and the separation distance between them is increased by a factor of 2?

Q 10 The Earth exerts a gravitational force of about 1 N on 100 gram mass. We call this force the weight. Calculate the weight of the battery (in Newtons), using the standard mass of a AA battery as 25 grams.

A spaceship is initially at rest on the surface of Mars where g = 4 m/s ^ 2 . The mass of the spaceship is 3000 kg. The engines ignite and there is an upward thrust force on the spaceship . After a period of 25 seconds of constant thrust, the spaceship has reached a velocity of the 600 m/s.  what is the acceleration?   What is the altitude of the spaceship at 25 seconds?

What is the mass of an object that weighs 250 N on the surface of the Earth where the acceleration due to gravity is 9.8 m/s²? What about the mass of a 250 N object on the Moon (g = 1.7 m/s?)? On Mars (g = 3.7 m/s²)?
