A block is pulled across a table by a constant force of 9.20 N. If the mass of the block is 2.30kg, how fast will the block be moving after 2.00 seconds? Assume negligible friction.

Explanation:

From Newton's 2nd Law, we have . Using this, we can find the acceleration of the object:

.

Now that we've found the block's acceleration, we can use the following kinematics equation to find its final velocity after 2 seconds:

*Assumption: The block is initially at rest and has a initial velocity of zero. Otherwise, the question is unsolvable.

total distance travelled = 60 miles

total time taken =1.5 hours

average speed = total distance / total time

60 / 1.5

= 40

therefore, average speed = 40 m/h

happy to

pls mark as brainliest

there is no correct list among the choices you've provided.

the list might look something like this:

-- baby human

-- piccolo

-- flute

-- soprano singer

-- trumpet

-- tenor singer

-- trombone

-- baritone singer

-- baritone horn

-- bass singer

-- tuba

since i had to make up the list myself, i made it easy on myself, and i didn't try to shuffle the string instruments and woodwinds into it too.
