Answer:
force is a derived quantity
work is a fundamental quantity
2.Force is measured in Newton why work is measured in Newton per seconds (N/s)
Explanation:
no
Answer with Explanation:
Newton's laws are applicable for inertial frames of reference which is a frame which is not accelerating when seen from the observer standing on earth.
For the person as he presses the brakes his frame is a decelerating frame of reference hence he cannot apply the newtons laws of motion as they are in their original form but if he analyses the motion he has to apply a correction known as pseudo-force on the object he is analyzing. Pseudo Force has no basis in newton's laws but are a correction that needs to be applied if he wishes to analyse the motion from non inertial frame of reference
While as a person standing on earth outside the car since his frame is an inertial frame of reference he can apply newton's laws of motion without any correction.
Answer:
The answer should be C. slanted upward to the right.
Hope this helps. :-)
Explanation:
The weight of the car is equal to, ...........(1)
Where
m is the mass of car
g is the acceleration due to gravity
The normal or vertical component of the force is,
or
.............(2)
The horizontal component of the force is,
Taking ratio of equation (1) and (2) as :
or
Hence, this is the required solution.
