Question

find the value of x by solving

Answer 1

Given :

( 150 m/s )² = ( 100 m/s )² + 2 ( 50 m/s² ) x

= > 150 m/s × 150 m/s = 100 m/s × 100 m/s + 100 m/s² x

= > 22500 m²/s² = 10,000 m²/s² + 100 m/s² × x

= > 100 m/s² × x = 22500 m²/s² - 10,000 m²/s²

= > 100 m/s² × x = 12,500 m²/s²

= > x = 12,500 m²/s² / 100 m/s²

= > x = 125 m

ANSWER :

x = 125 m
