Three kids pull on a toy. kim pulls with a force of 30 n north, jim pulls with a force of 30 n south, and tim pulls with a force of 15 n east. the acceleration of the toy is

As we can see the figure we will have

North

South

East

now for net force on Toy we need to add all forces along with the direction (Vector Sum)

now from above we have

towards East

so net force on the toy is 15 N towards East

now the acceleration of toy is given as

here m = mass of toy

Answer: it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.explanation:   we have equation of motion ,where s is the displacement, a is the acceleration, u is the initial velocity and t is the time taken.average velocity = displacement/ time taken.average velocity = 10.69 miles/hr = 10.69*1.6*1000/(60*60) = 4.75 m/s4.75 = s/ts = 4. 1we also have acceleration = 2.18 m/s², initial velocity = 0 m/sso it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.
