Question

An object is thrown downward from the top of a 175 meter building with an initial speed of 10m/s

Answer 1

Answer:

Explanation:

we can look for the final velocity of the object using the eqaution of motion as shown:

v² = u²+2gH

v is the  final velocity

u is the initial velocity = 10m/s

g is the acceleration due to gravity = 9.81m/s²

H is the height of the object = 175m

Subxtitute the given parameters inti the formula and get v:

v² = 10²+2(9.81)(175)

v² = 100+3433.5

v² = 3533.5

v = √3533.5

v = 59.44m/s

Hence the final velocity of the object is 59.44m/s
