Physics! Someone help me! Its due today please!

Assume a 9.0 kg bowling ball moving at 5 m/s bounces off a spring at 2 m/s.

(a) What is its change in velocity of the bowling ball?

(b) What is its change of momentum of the ball?

(c) What is the impulse exerted on of the ball?

(d) If the interaction with the spring occurs in 0.3 s, calculate the average force the spring exerts on the ball.

the best answer for these questions would be:

1.            c. is smaller

2.            d) concrete operational

3.            b) interaction with the environment – the children interact with their environment can them learn more.

4.            a) parents who reason openly with children can limit a child’s cognitive ability.

Ohm's law tells you that i = v/r where v is equivalent voltage and r is equivalent resistance of the circuit
since all circuits have the same voltage, your question is really asking which circuit has the lowest total resistance, since the lower the resistance, the higher the current
circuit a has a resistance of 5 ohms; circuit c is in series so has a resistance of 10 ohms; circuit b is in parallel and therefore has a resistance of 2.5 ohms (review your notes on adding resistances in parallel and series); therefore b has the highest current
