Answer:
19.12 m/s.
Explanation:
The following data were obtained from the question:
Final velocity (v) = 0 m/s
Breaking Acceleration (a) = – 4.57 m/s²
Distance (s) = 40 m
Initial velocity (u) =.?
The initial velocity of the car can be obtained as illustrated below:
v² = u² + 2as
0² = u² + (2 × –4.57 × 40)
0 = u² + (– 365.6)
0 = u² – 365.6
Collect like terms
u² = 0 + 365.6
u² = 365.6
Take the square root of both side
u = √365.6
u = 19.12 m/s
Therefore, the car was initially moving at 19.12 m/s.
The change from broken white lines to a solid line on the pavement markings of traffic signifies that overtaking from any side is not allowed or prohibited. The broken line signifies that you can overtake when safe.
Answer:
factors that affect the force of gravity between objects include their distance apart and their mass.
Explanation:
A dull knife is actually more dangerous than a sharp one because it forces you, as the chef, to add more pressure while cutting.
<h3>Why a dull knife is more dangerous than sharpen knife?</h3>
As the chef we have cut many things. Chef have to look over all the knifes whether it is sharp or dull and whether it is long or short, et.,. They have various knifes that can be used at various places by giving force and that force can be known to be pressure.
Pressure (symbol: p or P) can be defined as the force that can be applied perpendicular for the straight to the surface of an object which will be per unit area over and there the force is gets distributed.
Pressure formula can be, P = F/A N/m².
Thus, dull knife is more dangerous than the sharp, because of the pressure.
Hence, Option D is the correct answer.
