2. Batman stands triumphantly at the edge of a partially-opened steel gate. The gateis 4.00 m long and is supported by a pivot at the wall and a taut cable that attachesto a point 3.00 m along the gate from the wall. The gate itself is 950. kg, uniformin construction, and opened at a 70.0° angle from the wall. If Batman has a mass of1.00 x 102 kg, what is the tension in the cable and the x and y components of the forceprovided by the pivot at the wall? (Note: the resulting force from the pivot does notneed to be aligned with the 70° angle the gate makes with the wall!)70.0°3. Your car tires each have a radius of 0.300 m. You accelerate from a stoplight, reaching55.0 mph in 6.00 s. Assuming your acceleration was constant, what is the angularacceleration of each tire and how many revolutions does each one complete duringyour period of acceleration?
