The position of a particle, x at anytime, t is given by x=6-12t + 4t. What is the distance covered after 2 minutes?
Calculate the displacement of the particle from t1=2 seconds to t2= 5seconds
Find the velocity and acceleration of the particle at anytime.
Calculate the time the particle will be at rest
What is the initial position of the particle before the motion?
What is the maximum velocity of the particle?
Find the velocity of the particle at t=2

explanation: in any substance/object, the particles inside it (atoms/molecules) constantly move in random directions and with random speeds (this motion is called brownian motion). as a result, the particles have some kinetic energy (which is proportional to the temperature of the substance).

have a great day!

two charges are fixed in place on the x-axis as shown. the charge at x = 0 is negative and has magnitude q = 2 μcoulombs (1 μcoulomb = 10-6 coulombs). the charge at x = d, (d = +12 cm), is positive and has magnitude q = 4 μcoulombs. find a point x = xo along the x-axis at which the electric field is zero.
