A famous golfer strikes a golf ball on the ground, giving it an initial velocity v = v0xi + v0yj. Assume the ball moves without air resistance and its motion is described using a Cartesian coordinate system with its origin located at the ball's initial position. show answer No Attempt 25% Part (a) Determine the vertical component of the initial velocity, v0y, assuming the ball reaches a maximum height of 28 during the drive. Give your result in m/s.

Aparticle initially moving east with a speed of 20.0 m/s, experiences an acceleration of 3.95 m/s, north for a time of 8.00 s. what was the speed of the particle after this acceleration, in units of m/s? give the answer as a positive number.

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.

Need people build a dam to create a reservoir that supplies water a nearby city needs. describe two ways this action will likely affect the water cycle in the local environment. (5 points) worth 20 points
