Two balloons are separated by a distance of 25.5 cm. One balloon is charged with a charge of + 6.25 nC = + 6.25 x 10-9 C and the other balloon is charges with a charge of - 3.5 nC = - 3.5 x 10-9 C. Calculate the magnitude of Coulombic Force between them. Explain what kind of coulombic force will exist between them (attractive or repulsive)?

•• al and bert are jogging side-by-side on a trail in the woods at a speed of 0.75 m/s. suddenly al sees the end of the trail 35 m ahead and decides to speed up to reach it. he accelerates at a constant rate of 0.50 m/s2, while bert continues on at a constant speed. (a) how long does it take al to reach the end of the trail? (b) once he reaches the end of the trail, he immediately turns around and heads back along the trail with a constant speed of 0.85 m/s. how long does it take him to meet up with bert? (c) how far are they from the end of the trail when they meet?
