If X is 0.2 m, find the minimum force required to move the ball over the block. F Pivot point 0.5m X- 560N

True or false a high force means an object is moving fast100 points!

Why there is no inductive reactance in dc circuits

If a rock is thrown upward on the planet mars with a velocity of 12 m/s, its height (in meters) after t seconds is given by h = 12t − 1.86t2. (a) find the velocity of the rock after two seconds. m/s (b) find the velocity of the rock when t = a. 12−3.72a m/s (c) when will the rock hit the surface? (round your answer to one decimal place.) t = s (d) with what velocity will the rock hit the surface? m/s
