Answer:
They combine if they have the same units
Explanation:
I am not quite sure what you mean by this question. I will try my best to answer this.
Velocities combine only if they both have the same units. The linear velocities have the unit meters per second. For example, a linear velocity and an angular velocity cannot combine together because angular velocity has a unit of radians per second.
Answer:
The final kinetic energy of the two-car system is 60,000 J.
Explanation:
Given;
mass of the car, m = 1200 kg
time of motion, t = 8.8 s
final velocity of the car, v = 10 m/s
Apply the principle of conservation of kinetic energy; the initial kinetic energy is equal final kinetic energy.
Therefore, the final kinetic energy of the two-car system is 60,000 J.
Answer:
u = 104.68 m/s
Explanation:
given,
horizontal distance = 150 m
elevation of 12.4 m
angle = 8.6°
horizontal motion = x = u cos θ. t .............(1)
vertical motion =
................(2)
from equation(1) and (2)
..........{3}
u = 104.68 m/s
The initial speed of the ball is u = 104.68 m/s
True........don't blame me if i'm wrong.<span />
We have that the overhang possible for the two bricks are is mathematically given as
x=13.5m
Length of Overhang
Question Parameters:
A uniform brick of length 18 m
a maximum overhang of 9 m attained
<em>Length </em>18 m are stacked over the edge of a horizontal
surface.
Generally the equation that balances the moment is mathematically given as
x=13.5m
