Answer:
2100 J
Explanation:
Parameters given:
Force acting on the object, F = 420 N
Distance moved by object, d = 5m
The change in kinetic energy of an object is equal to the work done by a force acting on the object:
W = F * d
∆KE = F * d
∆KE = 420 * 5
∆KE = 2100 J
because a chemical change takes time
Answer:it causes the moving object to slow eventually stop
Explanation:
of motion f=ma is very important because it shows the relationship between force and motion. it allow you to calculate the acceleration and velocity and position. and object with know force is incredibly valuable for scientist,engineer, inventor etc.
