PLEASE HELP IMMA FAIL u are rolling a ball along the floor of a tub to try and make it fly out. u roll a 0.5kg ball along the bottem of the tub at 3m/s. the top edge of the tub is 0.5m above the bottem.

calculate the energy the ball would need in order to make it over the tub

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.

Did you ever figure out the right answers since you asked?

It has more electrons than an neutral object
