Question

An object is thrown horizontally off a cliff with an initial velocity of 5.0 meters per second. The object strikes the ground 3.0 seconds later. (i) What is the vertical speed of the object as it reaches the ground? a) – 29.4 m/s b) zero. c) 15 m/s.

d) 29.4 m/s
(ii) How far from the base of the cliff will the object strike the ground? a) – 44.1 m/s b) zero. c) 15 m/s. d) 29.4 m/s

Answer 1

Refer to the photo taken.

Answer 2

Below

Step-by-step explanation:

Vertical speed = at = 9.81 m/s * 3 = 29.4 m/s

For 3 seconds it travels 5 m/s horizontally = 15 meters (NOT m/s)
