The gravitational force on the rider is:
- Way up: equal to mg
- Way down: equal to mg
Explanation:
The choices are missing: find them in the attached figure.
The force of gravity acting on a body is a force directed downward (towards the Earth's centre) and whose magnitude is
where
m is the mass of the body
g is the acceleration due to gravity
The value of g is approximately constant near the Earth's surface and it is
During the ride, the mass of the rider, m, remains constant. This means that the magnitude of the gravitational force, mg, exerted on the rider remains constant during the rider.
Therefore, the correct answer is
- Way up: equal to mg
- Way down: equal to mg

Answer:
The mass of the object is 24.5 kg and weight of the object on Mars is 91.14 N.
Explanation:
Weight of the object on the surface of Earth, W = 245 N
On the surface of Earth, acceleration due to gravity, g = 10 m/s²
Weight of an object is given by :
W = mg
m is mass
So, the mass of the object is 24.5 kg
Acceleration due to gravity on Mars, g' = 3.72 m/s²
Weight of the object on Mars,
W' =mg'
W' = 24.5 kg × 3.72 m/s²
= 91.14 N
So, the weight of the object on Mars is 91.14 N.
