Question

a diver running 2.1 m/s dives out horizontally from the edge of a vertical cliff and 2.6 s later reaches the water below.

Answer 1

This is a question on projectile motion.

Range = The distance from the cliff where the diver will be after t seconds.

The range is the horizontal distance covered.

The horizontal distance is covered at a constant velocity.

Range = ut

Where u = initial velocity

t = time taken.

Range = 2.1 × 2.6 = 5.46M
