2. A block of mass 2.00 kg is moved up a 30.0" rough incline a distance of 3.00 m starting from rest. A spring with spring constant of 100 N/m is fastened to the top of the incline as shown in the figure. A force ofF = 15.0 N is acting on the block at an angle of 40' with the horizontal. (@) How much work is done by the gravitational force on the block? -29.4 J (b) How much work is done by the normal force on the block? 0 J (9 How much work is done by the 15.0-N force on the block? 44.3 J (d) Calculate work done by the friction force on the block? -12.9 J (e) Calculate the speed of the block right before touching the spring. 1.40 m's (f) The block compresses the spring by x and stops momentarily before it is pushed down by the spring.
