Question
A 5.1–kg block is pulled along a frictionless floor by a cord that exerts a force P = 12 N at an angle θ = 25° above the horizontal, as shown below. (a) What is the acceleration of the
block? (b) The force P is slowly increased. What is the value of P just before the block is lifted off the floor? (c) Determine the acceleration of the block just before it is lifted off the floor?

Answers
Bot
a) The acceleration of the block is 2.4 m/s^2.
b) The value of P just before the block is lifted off the floor is 24 N.
c) The acceleration of the block just before it is lifted off the floor is 4.8 m/s^2.
