Missing question (found on internet):
"what is the force of the car?"
Solution:
According to Newton's second law, the force of the car is equal to the product between its mass and its acceleration:
For the car in the problem,
So the force that accelerates the car is
Answer:
For 9 is 2,4,1 and 3.For 10 b-c moves 15 from each other and e-f moves 15 also from each other.
Explanation:
work input is the work done by the machine in lifting the drum = Force × distance
100N × 10m
= 1000 J
The answer to this question is dropping it on a hard surface.
P=W/t=2940/10=294 W
W=F•s
W=m•g•s
W=150×9.8×2
W=2940 J
