The net force is 270 N
Explanation:
We can solve this problem by using Newton's second law, which states that the net force on an object is equal to the product between its mass and its acceleration:

where
F is the force
m is the mass
a is the acceleration
In this problem, we have
m = 90.0 kg

Substituting, we find the net force on the object:

Answer:
√(6ax)
Explanation:
Hi!
The question states that during a time t the motorcyle underwent a displacement x at constant acceleration a starting from rest, mathematically we can express it as:
x=(1/2)at^2
Then the we need to find the time t' for which the displacement is 3x
3x=(1/2)a(t')^2
Solving for t':
t'=√(6x/a)
Now, the velocity of the motorcycle as a function of time is:
v(t)=a*t
Evaluating at t=t'
v(t')=a*√(6x/a)=√(6*x*a)
Which is the final velocity

Where is the Temperature bud?
Answer:
is the minimum gap between the slabs
Explanation:
Given:
- length of the concrete highway,

- coefficient of thermal expansion,

- range of temperature variation,

<u>Now form the equation of thermal expansion:</u>



Since each slab of the highway expands by the above length so the minimum gap between the slabs to prevent buckling:


is the minimum gap between the slabs
