Answer:
31-40 m/s
Explanation:
The kinetic energy of an object is given by :
m is mass of the object
v is velocity
If mass of an object is constant, its kinetic energy depends only on velocity. It means if the velocity is more, it will have maximum kinetic energy. For the interval of 31-40 m/s, the kinetic energy of the object is maximum.
Answer:
The Amount of work is done on the box by the net force is 378 Joules.
Explanation:
Given:
A 42 N net force is applied to a box which slides horizontally across a floor.
Force = 42 N
Force applied for a displacement of 9.0 m
Displacement = 9.0 m
To Find:
Amount of work is done on the box by the net force = ?
i.e Work = ?
Solution:
When a force causes a object to move, work is being done on the object by the force. Work is the measure of energy transfer when a force (F) moves an object through a distance (d).
Formula is given by
Substituting the given values we get
∴ Work = 42 × 9.0
∴ Work = 378 N-m
or
∴ Work = 378 Joules
The Amount of work is done on the box by the net force is 378 Joules.
