Answer:
Explanation:
Given
Beta rocket has twice the mass of Alpha engine
suppose alpha has a mass of m so beta has 2 m mass
Thrust force on alpha is F
thrust force on beta is 2 F
Acceleration of alpha
Acceleration of beat
Therefore acceleration of alpha and beta is same
Answer:
d. 4.0s
Explanation:
Mass = 0.1 kg
g = acceleration due to gravity = 10 m/s^2
Force = 0.1 × 10 = 1N
Distance = 2m
Time = force × distance / power
= 1 × 2/0.5
= 4.0 s
The right option is d. 4.0s
~686newtons on earth and
~1617 newtons on jupiter
the formula is weight = gravitational acceleration * mass of the object
