Acceleration of car is 4m/s²
Acceleration of truck is 2m/s²
Explanation:
Given parameters:
Force on the car and truck = 12000N
Mass of car = 3000kg
Mass of truck = 6000kg
Unknown:
Acceleration of car = ?
Acceleration of truck = ?
Solution:
Force is product of mass and acceleration. It is a push or a pull exerted on a body.
Force = mass x acceleration
Make acceleration the subject of the formula;
Acceleration =
Acceleration of car = = 4m/s²
Acceleration of truck = = 2m/s²

The formula for gravitational potential energy is ...
Grav PE = (mass) · (gravity) · (height)
We can see from this simple formula that mass and height have <em>EQUAL </em>influence on the Gravitational PE. If EITHER of them is multiplied by some factor, the Gravitational PE gets multiplied by the same factor.
So the answer to the question is: <em> No </em>.
Answer:
When light strikes translucent materials, only some of the light passes through them. The light does not pass directly through the materials. ... When light strikes an opaque object none of it passes through. Most of the light is either reflected by the object or absorbed and converted to heat.
The energy in food substances is released via chemical reactions that take place in the Mitochondria, which are present in some single celled organisms
The general equation for the forces acting on the passengers at the topmost point of the ferris wheel is
where
mg is the weight of the passengers
R is the normal reaction of the cabin
is the centripetal force
In order to feel weightless, the normal reaction felt by the passengers should be zero. Therefore, the equation becomes:
or
where
is the angular frequency of the wheel and r is its radius. Since we know its radius,
we can calculate the angular frequency:
From which we find the frequency at which the ferris wheel should rotate:
This is the number of revolutions per second, so the number of revolutions per minute will be
