please make me brainlist
Explanation:
The work done on an object is given by the formula:
Work = Force × Distance
Since the object comes to rest, the force applied is equal to the force required to stop the object, which is the negative of the kinetic energy of the object.
Kinetic energy = (1/2) × mass × velocity²
= (1/2) × 5 kg × (2 m/s)²
= 10 J
Since the object comes to rest, the work done is equal to the negative of the kinetic energy:
Work = -10 J
The distance over which this work is done is 6 m, so the force applied is:
Force = Work / Distance
= -10 J / 6 m
= -1.67 N (approximately)
Note that the negative sign indicates that the force is applied in the opposite direction of the motion, to slow down and stop the object.
Answer:
30
Explanation:
work done= force* displacement
force= mass*acceleration
acceleration= change in velocity
v/a -2m/s
m-5kg
s-6m
f=m*a
=5*2
=10N
work=f*s
=10*6
=60Nm or 60J
