Aman runs at a velocity of 4.5 m/s for 15.0 min. when going up an increasingly steep hill, he slows down at a constant rate of 0.05 m/s^2 for 90.0s and comes to a stop.
how far did he run?

The membrane surrounding a living cell consists of an inner and an outer wall that are separated by a small space. assume that the membrane acts like a parallel plate capacitor in which the effective charge density on the inner and outer walls has a magnitude of 7.0 × 10-6 c/m2. (a) what is the magnitude of the electric field within the cell membrane? (b) find the magnitude of the electric force that would be exerted on a potassium ion (k+; charge = +e) placed inside the membrane.
