Question 4 (1 point) A student in a lab exerts a 25 N force to pull a block a distance of 48 cm. If a total of 11 J of work is done, the angle between the force and the displacement is: O 1) 660 ( 2) 610 ( 3) 890 ( 4) 240 5) 150 Question 5 (1 point) A 12-kg block sliding across a smooth table at 1.9 m/s hits a spring bumper with a force constant of 490 N/m. What is the maximum compression of the spring? ( 1) 0.30 m ( 2) 0.40 m ( 3) 0.20 m ( 4) 0.50 m (5) 0.10 m Question 6 (1 point) A 10.0 kg crate slides across the floor 13 m against a force of friction of 7.5 N. The thermal energy produced is: ( 1) 17 J ( 2) 49 J ( 3) 980 J ( 4) 75 J (5) 98 J
