dens = mass/volume. after crushing, vol less so density more. the actual density of the metal is the same, density of can changes
Answer:
ans: 6 m/s
Explanation:
spaceship 1 has mass= 150kg
initial momentum of spaceship 1 = 900 kg•m/s
we know,
momentum = mass × velocity
so,
velocity = momentum/mass
= 900 / 150
= 6 m/s
since we know it was initial momentum so, velocity is initial speed,
Answer:
The position is relative to the base of the ocean
Explanation:
From the question we are told that
The angle made by the incline with the horizontal is
The constant acceleration is
The distance covered is
The height of the cliff is
The velocity of the car is mathematically represented as
The initial velocity of the car is u= 0
So
substituting values
The vertical component of this velocity is
substituting values
The negative sign is because is moving in the negative direction of the y-axis
The horizontal component of this velocity is
Now according to equation of motion we have
substituting values
using quadratic equation we have that
given that time cannot be negative
The car’s position relative to the base of the cliff when the car lands in the ocean is mathematically evaluate as
substituting values
