Robert applies a 27.95 n-s impulse to rebecca while ice skating. if rebecca, whose mass is 59.11 kg, left robert's hands at 6.129 m/s after he pushed her, how fast was rebecca moving before the push?

As per Impulse momentum theorem we know that

Impulse = final momentum - initial momentum

so now here we have

impulse = 27.95 N-s

mass = 59.11 kg

final speed = 6.129 m/s

now we have

so initial speed must be 5.656 m/s

i think they are all correct

explanation:

they seem good
