1.8 Diver 8 A diver whose gender is not relevant jumps upward at 4 m /s from a 10 m diving board. How fast is he/she moving when he/she strikes the water? Answer in m/S. Enter answer here1.6 Museum Pendulum 6a The pendulum at the Houston Museum of Natural Science has an amplitude of 1.5 m and a period of T = 8 s . The position of the bob is therefore described by: x = 1.5 sin ( It). Enter a formula for the velocity versus time in terms of t. Do not enter "v=", just put the formula. t should be the only variable since you have values for everything else. Type "pi" for 3.14. Denote multiplication with *. Make sure the preview matches your intended answer before you submit. NOTE: You have to enter the expression using whole numbers and "pi". Preview will appear here...

Enter answer here\f1.10 Rocket 10 The engines of a rocket sitting on the ground fire to accelerate the rocket at 3.5 m/s' until it reaches an altitude of 1.2 km. At that point the engines fail and the rocket is in free fall. What height does the rocket reach in m? Assume a constant acceleration of gravity of 9.8 m/seven at these high altitudes.
