(a) What is the tangential acceleration of a bug on the rim of a
6.0 in. diameter disk if the disk moves from rest to an angular
speed of 79 revolutions per minute in 4.0 s? m/s2 (b) When the disk
is at its final speed, what is the tangential velocity of the bug?
m/s (c) One second after the bug starts from rest, what is its
tangential acceleration? m/s2 What is its centripetal acceleration?
m/s2 What is its total...
A centripetal acceleration can a) Change an object’s direction.
b) Change an object’s speed.
A tangential acceleration can a) Change an object’s direction. b)
Change an object’s speed.
An object moves in a straight line at a constant speed
An object moves in a circle at a constant
An object moves in a straight line while slowing to a stop
The acceleration… a. Points parallel to the velocity, and in the
same direction. b. Points parallel to...
Suppose that a particle has the following acceleration vector
and initial velocity and position vectors.
a(t) = 7 i +
v(0) = 4 i
= j + 5 k
Find the velocity of the particle at time t.
Find the position of the particle at time
