Answer:

Answer should be (B)

Explanation:

If the forces on an object are balanced (or if there are no forces acting on it), this is what happens: a stationary object stays still. a moving object continues to move at the same speed and in the same direction.

ALSO: forces acting upon an object are balanced, then the object will maintain its state of motion. To maintain the state of motion is to keep the current speed and direction. But if the forces are not balanced, the object will change its state of motion.

Suppose a pulley with an IMA of 2 was used with an input force of 50 N to lift a box 45 cm that weighs 100 N. What distance was
IRINA_888 [86]
The ideal mechanical advantage (IMA) is the number of times in which the input force is multiplied under ideal conditions. If the real force was only 50N, the distance at which the rope was pulled will be twice the distance given in this item. The answer is 90 cm.

Two children stand on a platform at the top of a curving slide next to a backyard swimming pool. At the same moment the smaller
IgorC [24]

Answer:

Explanation:

i )

In a conservative field like gravitational field , loss of potential energy  or work done , depends upon the initial and final point and not the manner in which 2 nd point has been reached . Since the initial and final point is same in both the cases of straight and curved path , final velocity will remain same for both of them .

Hence , due to increased mass of larger child , his kinetic energy will be greater .

ii ) Since the initial and final point is same in both the cases of straight and curved path , final velocity will remain same for both of them .

iii ) Smaller child undergo free fall , therefore , he will fall with acceleration g . The larger child falls on curved path . So , he will have only a component of

vertical g at any moment  . hence average acceleration  will be less.
