PHYS 201 Midterm: PHYS 201 TAMU 201Fall 09 Exam 2
Document Summary
No work needs to be shown. (6 pts) 1. A small block with mass m = 0. 20 kg moves on the inside of a circular track that has the shape of a vertical circle with radius r = 2. 0 rn. When the block is at the top of its circular path its speed is v = 6. 0 rn/s. At this point the normal force that the track exerts on the block has magnitude. 4 (a) 8. 36 n (b) 5. 56 n (c) 4. 44 n (d) 1. 96 n (e) 1. 64 n (f) none of the above values (6 pts) 2. A satellite is in a circular orbit around a planet that has mass 9. 60 x 1023 kg. The constant orbital speed of the satellite is 4500 rn/s. The acceleration of the satellite in its orbit is (a) zero (b) 1. 26 rn/s2 (c) 4. 00 rn/s2 (d) 6. 40 rn/s2 (e) 9. 80 rn/s2 (f) none of the above values (6 pts) 3.
