A particle is executing circular motion. The velocity of the particle changes from zero to (0.3i+0.4j) m/s in a period of 1 second. The magnitude of average tangential acceleration is:
A. 0.1 m/s/s
B. 0.2 m/s/s
C. 0.3 m/s/s
D. 0.5 m/s/s
I know the answer is D, but how is this problem solved?
What is "i" and "j" ?

A particle undergoes uniform circular motion. This means that it moves in a circle of radius R about the origin at a constant speed. The position vector of this motion can be written Here, analogous to the simple harmonic motion problem of HW 1, ω is the angular frequency and has units of rad/s 1/s and can also be written in terms of the period of the motion as 2π (a) Show that the particle resides a distance R away...

A particle object undergoes uniform circular motion at a speed v around a circle of radius r. Given v and r, the magnitude of centripetal acceleration is a0. Assume when either v or r are changed, the particle remains in uniform circular motion. 1. Suppose the radius of the circle is cut in half. What happens to the magnitude of the centripetal acceleration? choices: the acceleration doubles, acceleration increases by square root of 2, acceleration remains the same, acceleration decreases...
