Asked by Amanda
I am trying to study for my exam i have tomorrow and this type of problem keeps giving me trouble can someone please help me::
A 3.24 kg block located on a horizontal frictionless floor is pulled by a cord that exerts a force F=11.8N at an angle theta=23.0degrees above the horizontal, as shown. What is the magnitude of the acceleration of the block when the force is applied?
b)What is the horizontal speed of the block 4.50 seconds after it starts moving?
c)If, instead, the floor has a coefficient of kinetic friction µk = 0.04, what is the magnitude of the frictional force on the block when the block is moving?
d)What is the magnitude of the acceleration of the block when friction is being considered?
