If a Ferrari, with an initial velocity of 14m/s, accelerates at a rate of 60 m/s^2 for 4 seconds, what will its final velocity be?*

254

Explanation:

use the formula "final Velocity- initial velocity / time = acceleration"

so "X - 14 /4 = 60"

60 x 4 = X - 14

240 +14 = X

X = 254

the force required to move the cart is divided by three or 33.33 n.

electric field is a function of 1/r^2

yes, the force per unit charge for a point charge is inverse square law.
