A5.44 kg block initially at rest is pulled to the right along a horizontal, frictionless surface by a constant horizontal force of 7.4 n. find the block's speed after it has moved 4.9 m.

v = 3.65 m/s

Explanation:

It is given that,

Mass of the block, m = 5.44 kg

Horizontal force acting on the block, F = 7.4 N

We need to find the speed of the block after it has moved 4.9 meters. It can be calculated using the work energy theorem as:

v = 3.65 m/s

So, the speed of the block is 3.65 m/s. Hence, this is the required solution.

explanation:

as the height from which the ruler was dropped increased, the speed of the ruler at ryan's hand increased.
