1. An m= 1.5 kg block is initially at rest on a frictionless horizontal surface. It is pulled along the surface with a constant force of F = 3.8 N at an angle of 0 = 30° above the horizontal. m (a) Draw a free body force diagram (FBD) for the block. (b) What is the block's horizontal acceleration? (c) How long must the block be pulled before its speed reaches v,= 5.2 m/s? (d) What distance d does the block move during this time? What is the block's vertical acceleration? (e) (f) Before doing any calculations: Is the normal force N acting on the block equal to, less than, or greater than the weight of the block? Explain your reasoning. (8) Find the normal force N acting on the block. Is your answer consistent with your answer to (f)? (h) [General question] Under what condition(s) is the normal force acting on an object equal to the weight of the object?
