Higher Physics Homework Answers.
Hi Physics lovers, here are the answers to the homework problems 1.24 to 1.29
1.24 Displacement = -30.6m so depth = 30.6m
1.25 Displacement = -0.82m so height dropped = 0.82m
1.26 (a) 0m/s
(b) 10m
(c) -14m/s ie 14m/s going down
(d) 2.86s
1.27 (a) From the instant it is released it will be subject to negative acceleration -9.8m/s2 So its velocity will decrease to zero and then increase negatively until it strikes the ground.
(b) Displacement = -32.1m so height = 32.1m
(c) Final velocity = -25.4m/s
1.28 (a) 1.53s
(b) 11.5s
(c) 14.7m
1.29 (a) 6.1s
(b) 183.7m
