Answer:
C. 750 N. left
Explanation:
let the force to the right be positive, and the left be negative
Step one:
given
mass of crate m= 500N
1450N force left
Frictional force of 200 N -----this opposes the motion
500 N opposing force to the right
The net force is equal to the summation of all the forces in Newton
Net force= -1450+200+500
Net force=-750N
The direction is right
Airports use ramps to connect the plane to the airport and towing trucks use ramps to get the vehicles on the truck
You are correct the answer would be C
hope i helps
Answer:
2) zero acceleration
Explanation:
Motion can be defined as a change in the location (position) of a physical object or body with respect to a reference point.
This ultimately implies that, motion would occur as a result of a change in location (position) of an object with respect to a reference point or frame of reference i.e where it was standing before the effect of an external force.
Mathematically, the motion of an object is described in terms of time, distance, speed, velocity, position, displacement, acceleration, etc.
In physics, acceleration can be defined as the rate of change of the velocity of an object with respect to time.
Generally, an object is said to be in equilibrium when neither the energy possessed by the object not state of motion changes with respect to time. Thus, the vector sum of all the forces acting upon an object that's in equilibrium is zero.
In conclusion, an essential characteristic of an object in equilibrium is zero (0) acceleration because there's no change in its velocity with respect to time.
