The motion of a freely falling object is an example of:
RRB Technicians Grade-III
24/12/2024 / Shift I
2024
✓ Answer:CUniformly accelerated motion
Near Earth's surface, g is approximately constant, so free fall is uniformly accelerated when air resistance is neglected.
52
A ball of mass 0.5 kg is thrown vertically upward and reaches 20 m. What is its initial speed? Take g = 10 m/s².
RRB ALP (Stage-I)
28/11/2024 / Shift I
2024
✓ Answer:A20 m/s
u = √(2gh) = √400 = 20 m/s.
53
The gravitational force between two objects is F. If both masses are halved without changing separation, the new force is:
RRB Group-D
16/11/2018 / Shift I
2018
✓ Answer:DF/4
F' = G(m₁/2)(m₂/2)/r² = F/4.
54
An object weighs 60 N on Earth. What is its weight on the Moon if lunar gravity is one-sixth of Earth's?
The source selects D, contrasting it with the Moon orbiting Earth. More precisely, Earth and Moon both orbit their common centre of mass under gravity.
60
An object is thrown vertically upward at 10 m/s. What maximum height does it reach? Take g = 10 m/s².
RRB Technicians Grade-III
20/12/2024 / Shift III
2024
✓ Answer:B5 m
h = u²/(2g) = 100/20 = 5 m.
