Billy pulls his friend sue on a sled at a constant velocity with the horizontal force of 200 n. the weight of the sled and sue is 400 n. which way will the sled move if billy suddenly starts to pull with the force of 600 n?

Initially sled is moving with uniform velocity which means the net force must be balanced on the sled

So it is given that applied force on the sled is 200 N and sled is not accelerating so friction force must be 200 N.

Now suddenly it starts with 600 N applied force due to which it will accelerate and this can calculated by Newton's II law

So in this case the sled ill start accelerating with acceleration

from 1609, galileo galilei used the recently invented telescope to observe the sun, moon and planets. he saw the mountains and craters of the moon, and for the first time revealed the planets to be worlds in their own right. galileo also provided strong observational evidence that planets orbited the sun.

his discoveries about the moon, jupiter's moons, venus, and sunspots supported the idea that the sun - not the earth - was the center of the universe, as was commonly believed at the time.galileo turned his gaze toward venus, the brightest celestial object in the sky - other than the sun and the moon.

i tried it and took the test

if im wrong then we have different tests
