A model rocket is launched straight upward with an initial speed of 50 m/s. It
accelerates with a constant upward acceleration of 2.0 m/s until its engines
stop at an altitude of 150 m.
(a) Describe the motion of the rocket after its engines stop. [Use everyday
language, as if you’re talking to your grandmother.]
(b) Calculate the maximum height reached by the rocket. [Label all kinematics
charts clearly.]
(c) How much time in total is the rocket in the air? Justify your answer.

Although light from the sun appears white, it is actually made up of a lot of different colors. this portion of the electromagnetic spectrum, we call white light is referred to as within the electromagnetic spectrum.

Give your knowledge of these things in your paper, you will compare and contrast analog and digital signals to determine which is more reliable for encoding and transmitting information. you’ll compare these features: signal shape numerical values for signal measurements amount of data that can be transmitted energy requirements privacy and security (ability of the signal to be encoded in a secret code) clarity of signal in the space provided, write down what you already know about any of these features. if you’re not sure, write down questions you might have about the features.

Two horses begin at rest. after a few seconds, horse a is traveling with a velocity of 10 m/s west, while horse b is traveling with a velocity of 13 m/s west. which horse had a greater acceleration? a. horse a because its change in velocity was greater than horse b's in the same time. b. horse b because its change in velocity was greater than horse a's in the same time. c. horse b because its change in velocity was the same as horse a's, but it took less time. d. both horses had the same acceleration.
