Answer:
Two objects will have the equal velocities but the forces on both of them will not be equal. The equal velocities of these objects are due to their equal acceleration.
Explanation:
From the newton's equation
so here we can say that velocity does not depends on the mass.
The acceleration of both objects will be same but not the forces because
F = Ma
As the force is depending on the mass so it will not be the same for both objects.
Answer:
W = 750 Joules.
Explanation:
Given that,
Force acting on the object, F = 50 N
Distance moved by the object, d = 15 m
To find,
Work done by the object
Solution,
Let W is the work done by the object. It is given by the product of force and distance. Its expression is given by :
Here, (force and distance are in same direction)
W = 750 Joules
So, the work done by the force is 750 Joules.
