Dont know brother

Yogita Ingle 3 years, 9 months ago

initial velocity, u = 6 m/s and final velocity, v= -4.4 m/s

time = 0.04s

thus acceleration = (v-u)/t

a =(- 4.4 - 6)/ 0.04 = -10.4/ 0.04 = -260 m/s²

Note: v is taken as negative because it's in opposite direction as that of initial velocity.
