To solve this problem, apply the concepts related to the relationship given between the centripetal Force and the Weight.
The horizontal force component is equivalent to the weight of the car, while the vertical component is linked to the centripetal force exerted on the car, therefore,
Equating both equation we have that,
Rearranging to find the angle we have that,
Our values are given as,
Therefore the minimum angle will be 11.53°
<span>Using Newton’s 2nd
law, we can calculate for the force (F) required to give a mass 255kg an
acceleration of 3.5 m/s^2: </span><span>
F= ma</span>
<span>F= 255kg*3.5m/s^2 = 892.5 N </span>
892.5 was the force needed for the motorcycle alone. Taking
into account the total resistance of 400N:
total F = 892.5 N + 400 N
<span>total F= 1292.5 N</span>
Troposphere is much warmer than the Stratosphere.
<u>Explanation:</u>
- The troposphere is the last and the lowest level of the atmosphere, so it is in close contact with the Earth's surface.
- On the other hand, the stratosphere is located above the troposphere, so it is not in contact with the Earth's surface.
- So from the above discussion, the troposphere is warmer than the stratosphere.
Answer:
30m/s
Explanation:
From law of motion equation
Vf= Vi + at
Where Vf= final velocity
Vi= initial velocity=0(the car started at rest)
a= acceleration= 3m/s2
t= time= 10s
Then substitute into the equation to get the final velocity.
Vf= 0+(10×3)
Vf= 30m/s
Hence, the car's final velocity is 30m/s
Solid. And it's where molecules don't move at all which means that no energy is required at all.
