A certain force exerted for 0.5 s raises the speed of an object from 2.4 ms to 4.9 ms. later this same force is applied for 2.5 s. how much does the speede of the object change in 2.5 second?

F = mass x acceleration (a) and a = v/t = 2.5/.5 = 5m/s/s;Then if you apply same force later it will give same acceleration of 5m/s/s soafter 2.5 seconds its velocity change is 2.5 x 5 = 12.5 m/s

The force exerted on a surface divided by the area over which the force is exerted?
Pressure is the force exerted on an object divided by the area where the pressure was applied.
Is work done every time forces are exerted on an object?
No. Only when there is also movement. The basic formula for work is: work = force x distance If a certain force is applied along a certain distance, then work is done.
What must be exerted on an object to change the angular momentum?
A torque.
Why must a force be exerted on an object to change its velocity?
To overcome the objects inertia
When the force applied an object is doubled how does the pressure exerted on the object changes?
When the force is doubled the pressure is doubled as well. Read Newton's law.
When the double force applied on the object then how does the pressure exerted on the object change?
When the double force applied on the object then the pressure exerted on the object will also be doubled.
What is the name to the force exerted by the first object on a second object?
applied force
The force exerted on a surface divided by the area over which the force is exerted?
Pressure is the force exerted on an object divided by the area where the pressure was applied.
What is applied to an object by a certain amount the acceleration will change by the same amount?
net force
What is the name given to the force exerted by the first object on a second?
applied force
Is work done every time forces are exerted on an object?
No. Only when there is also movement. The basic formula for work is: work = force x distance If a certain force is applied along a certain distance, then work is done.
What must be exerted on an object to change the angular momentum?
A torque.
What is internal and external forces?
An internal force is a force acted upon by an object to force another object's movement internally. An external force is a force exerted on an object based on the objects position and force applied on the object which causes the opposite forces change in motion.
A measure of the gravitational force exerted on an object its value can change with the location of the object in the universe?
Weight
