If the block of ice weighed 500 Newtons instead of 400 Newtons, how much force would the guy on the ramp have to exert to slide it up the ramp at constant speed? Hint: the angle of the ramp is 30 degrees so to find the force use F = Wsin30

Answer(b) 60 miles per hour;

How are period and frequency related to each other? dperiod is the reciprocal of frequency.

Since you have not included the experiment situation and the data, of course, i can not give you specific details about it. but i can you with this question.1) i will assume that the motion is projectile (parabolic) motion.2) yes, the horizontal distance depends on the horizontal velocity as, naming vx the horizontal velocity and t the time, it is: x = vx × t3) now, observe that the flight time depends on the vertical velocity as, naming voy the initial vertical velocity, t the time and y the vertical distance before reaching the ground: y = yo + voy×t - gt² / 2.the higher the initial vertical velocity (voy) the longer the object will be flying and so t will be higher in the equation for the horizontal distance.that explains the relationship between the horizontal distance and the horizontal velocity.
