Answer:

The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object

Answer: Newton's second law states that acceleration of a particle is dependent on the forces acting upon the particle and the particle's mass.

Explanation: Newton's second law of motion pertains to the behavior of objects for which all existing forces are not balanced. The second law states that the acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object. The acceleration of an object depends directly upon the net force acting upon the object, and inversely upon the mass of the object. As the force acting upon an object is increased, the acceleration of the object is increased. As the mass of an object is increased, the acceleration of the object is decreased.

What is the relationship between velocity and kinetic energy?

faltersainse [42]

Answer:

when an object has more velocity, it tends to have less potential energy and more kinetic energy.

Explanation:

kinetic energy is the energy of movment and velocity helps to describe movement

Sally travels by car from one city to another. She drives for 30 min at 80 km/hr, 12.0 min at 105 km/hr, and 45 min at 40.0 km/h

Anna [14]

Given :

Sally travels by car from one city to another. She drives for 30 min at 80 km/hr, 12.0 min at 105 km/hr, and 45 min at 40.0 km/hr.

To Find :

The total distance traveled.

Solution :

Total distance traveled is given as sum :

Distance = sum of product of speed and time

D = (v₁ × t₁) + (v₂ × t₂) + (v₃ × t₃)

Putting all given value in this we get :

$D = 80\times \dfrac{30}{60} + 105 \times \dfrac{12}{60} + 40\times \dfrac{45}{60}\\\\D = 91\ km$

Hence, this is the required solution.

if a book of mass 50 kg is placed on the table of mass 200 kg what will be the weight of table and reaction of table on the book

ollegr [7]

Answer:

See the answer below.

Explanation:

The weight of the table should be equal to the weight of the table plus the weight of the book.

$w_{table}=m_{table}*g\\w_{table}=200*9.81\\w_{table}=1962[N]$

And for the book

$w_{book}=m_{book}*g\\w_{book}=50*9.81\\w_{book}=490.5[N]$

And the total weight

$w = w_{table}+w_{book}\\w=1962+490.5\\w = 2452.5 [N]$

For the system to be in balance, the reaction force exerted by the table on the book must be equal to the weight of the book. This force in physics is known as the normal force.

$N_{force} = w_{book}\\N_{force}=490.5[N]$
