deceleration = a m/sec²
u = 300 m/sec
s = 10 cm = 0.1 m
v = 0
v² = u² + 2 a s
a = (0² - 300²) / (2 * 0.1)
a = - 4,50,000 m/sec²
u = 300 m/sec
s = 10 cm = 0.1 m
v = 0
v² = u² + 2 a s
a = (0² - 300²) / (2 * 0.1)
a = - 4,50,000 m/sec²

Thank u♥
u , s, v, a, stands for?
u = initial speed. v = final speed. a = acceleration/deceleration. s = distance travelled... these are usual symbols. so did not mention
thank uuuu
