Question

1) Calculate the range for an object that is launched at an angle of 27.00 degrees above the horizontal and an initial height of 1.50m. the initial speed is 190.00 m/s.

2)an astronaut brings a simple pendulum to another planet and performs an experiment. the astronaut measures the period of the pendulum for several different lengths and then plots the data as a log[Period] vs. log[Length] graph. the equation of the line is y=0.503x + 0.0500. determine the acceleration due to gravity on this planet

3)a student performs an experiment to determine the coefficient of static friction between a wooden block and a wooden ramp. the ramp is slowly raised until the block just begins to slide and the angle of the ramp is measured. if the average angle that is measured is 21.0 degrees, then what is the coefficient of static friction ?

please answer those question and explian, I learn better visually
