A bouncing ball is traversing a semi-circular path of radius 0.7 m. After every bounce the ball traverses with constant speed. From the point at which the ball bounces for the first time, there are laser beams placed 1 m apart at a height of 0.5 m from the ground. There are 20 such laser beams. The ball passes above each laser beam, below each laser beam, or through each laser beam. (Assume that the path and speed of the ball does not change if it passes through a laser beam).
Find the number of times the ball passes above the laser beam.
Q.76 Two different two-digit natural numbers are written side by side such that the larger number is written on the left of the smaller number. When the absolute difference of the two numbers is subtracted from the four-digit number so formed, the number obtained is 5481. What is the sum of the two twodigit numbers?
P is a point outside a circle with center O and radius 6 units, such that OP = 10 units. Tangents are drawn from P to the circle touching it at M and N, as shown below. The line segment OP cuts the circle at point C and the tangent drawn to the circle at C meets PM and PN at points A and B respectively. What is the length (in units) of the inradius of triangle ABP?
