An astronaut weighing 193 lbs on Earth is on a mission to the Moon and Mars.
(a) What would he weigh in newtons when he is on the Moon? The acceleration due to gravity on the Moon is one-sixth that
on Earth.
(b) How much would he weigh in newtons when he is on Mars, where the acceleration due to gravity is 0.38 times that on
Earth?
N
(c) What is his mass in kilograms on Earth?
kg
(d) Which of the following are true? (Select all that apply.)
His mass on the Moon is exactly equal to his mass on Earth.
His mass on the Moon is smaller than his mass on Earth.
His mass on Mars is smaller than his mass on Earth.
His mass on Mars is exactly equal to his mass on Earth.

His mass on Mars is greater than his mass on Earth.
Mass of an apple is 102 g. Calculate its weight if g ≈ 9.8 m/s2
The value 9.8 m/s2 is the average acceleration of a falling object due to the force of gravity on Earth.
In SI weight base unit is kg⋅ m⋅ s−2 or newton (N).
On a spending spree in Malaysia, you buy an ox with a weight of 28.9 piculs in the local unit of weights: 1 picul = 100 gins, 1 gin = 16 tahils, 1 tahil = 10 chees, and 1 chee =10 hoons. The weight of 1 hoon corresponds to a mass of 0.3779 g. When you arrange to ship the ox home to your astonished family, how much mass in kilograms must you declare on the shipping manifest? (Hint: Set up multiple chain-link conversions.)

- The total force on an object is ( 20 ı ^ + 40 ȷ ^ ) Newtons. Its acceleration is ( 4 ı ^ + 8 ȷ ^ ) m/s2. Calculate the object's massarrow_forwardWeight 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?
