5m
Explanation:
Given parameters:
Energy = 35J
Force on object = 7N
Unknown:
Distance moved = ?
Solution:
The energy on the car will cause the car to do work . When work is done, a force moves a body in particular distance. We can see that energy and force are related:
Energy = force x distance
Distance =
Inputting the parameters:
Distance = = 5m

Answer:
The astronaut will be propelled towards the shuttle at the rate of 0.4 m/s.
Explanation:
Given;
mass of the astronaut, m₁ = 95 kg
mass of the hammer thrown, m₂ = 2 kg
velocity of the hammer, v₂ = 19 m/s
let the recoil velocity of the shuttle = v₁
Apply the principle of conservation of linear momentum;
m₁v₁ = m₂v₂
v₁ = m₂v₂/m₁
v₁ = (2 x 19) / 95
v₁ = 0.4 m/s
Therefore, the astronaut will be propelled towards the shuttle at the rate of 0.4 m/s.
The acceleration due to gravity on a large body is given by:
acceleration = (gravitational constant * mass of body) / radius²
For b, this is:
g = GM/r²
M = gr²/G
For a,
g(a) = 1/6 g
r(a) = 1/4 r
M(a) = g(a)r(a)²/G
M(a) = 1/6 g * (1/4 r)²/G
M(a) = gr²/96G
The fraction is given as:
M(a) / M = (gr²/96G) / (gr²/G)
M(a) / M = 1/96
The mass of planet a is 1/96 of the mass of planet b.
