Answer:
In mine I said to build the boat accordingly based on what is going to be in it
Explanation:
just remember the density of the boat cannot change but the volume and the mass can
Answer:
Acceleration of the bullet while moving into the clay is -312500 ms⁻²
Explanation:
Given data
Initial velocity (v₁) = 250 m/s Final velocity (v₂) = 0 m/s
Distance (s)= 0.1 m acceleration (a) = ?
Using 3rd equation of motion
2as = v₂²- v₁²
2 × a × 0.1 = 0² - 250²
0.2 × a = -62500
a = -62500/0.2
a = -312500 m/s²
Here negative sign indicate that bullet slow down and it is deceleration i.e negative acceleration.
Answer:
the jet i just took the test
and got 100
Explanation:
Answer:
(a) Projectile B will travel 4 times as far as projectile A prior to landing
Explanation:
Initial velocity = v
Angle at which the projectile is shot at = θ
g = Acceleration due to gravity
Range of a projectile is given by
When Initial velocity = v
When Initial velocity = 2v
Dividing the equtions, we get
Here, the angle at which the projectiles are fired at are equal.
Hence, projectile B will travel 4 times as far as projectile A prior to landing
