Answer:
I think it's A, I'm not sure though
It's true
work measure by joule.
Energy = work/time
= joule/s .
and joule/s represents watt
Answer:
Solon,
total mass (kg)= 100kg
height (h)= 25m
acceleration due to gravity = 9.8m/s²
so,
work done =m*g*h
= 100*9.8*25
= 24,500 joule
Answer:
option C
Explanation:
The correct answer is option C.
For negative velocity
Negative velocity is when the velocity of the object in a negative direction.
so, for the velocity of the car to be negative, it should be in -x-direction.
For positive acceleration
Positive acceleration is the change of the velocity of the object with respect to time in a positive direction
but when the velocity of the object is in negative direction the slowing down of the vehicle will give positive acceleration.
hence, the correct answer is an option -x-direction decreasing in speed.
