Assuming the the car is travelling to the right (→):
The information we know:
Using one of the equations of motion:
Answer:
60m/s
Explanation:
since the object is falling under the influence of gravity, the formula is
v = u +gt
before the fall, the object is at rest then
u = 0m/s
v = 0 + 10×6 because acceleration due to gravity is g which is given as 10m/s2
therefore, v = 60m/s
Explanation:
Hi there!
Mass of the container (m) = 15000 kg
Also from the figure;
Volume of the container (V) = l*b*h
{ From figure length = 2m , breadth = 1.1m, height = 2.5m}
So,
V = (2*1.1*2.5) m³
= 5.5m³
Then;
Density (d) = m/v
= 15000/5.5
= 2727.27 kgm³
Therefore, the density is 2727.27 kgm³.
Hope it helps!
The one that's completely submerged is displacing more water, so the buoyant force on it is greater.
