Question

Sachi wants to throw a water balloon to knock over a target and win a prize. The target will only fall over if it is hit with a force of 0. 035 N. The water balloon has a mass of 11. 4 grams. How fast will Sachi have to make the water balloon accelerate to hit the target with enough force and win the prize? Round the answer to the nearest one tenth m/s2. The water balloon must accelerate m/s2.

Answer 1

Hi there!

We can use the following equation (Newton's Second Law):

∑F = ma

m = mass of object (kg)

a = acceleration (m/s²)

We can rearrange to solve for 'a':

F/m = a

Remember to convert grams to kg.

1000g = 1 kg

0.035/(0.0114) = 3.07 m/s²
