Document Summary
0. 20 kg moves on the inside of a circular track (6 pts) 1. A small block with mass m that has the shape of a vertical circle with radius r = 2. 0 m. 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 (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. 2 (c) 4. 00 m (e) 9. 80 rn/s2 (f) none of the above values (6 pts) 3.
