Question 1

A particle moves at a constant speed in a circular path with a radius of 2.06 cm. If the particle makes four revolutions each second, what is the magnitude of its acceleration?

◦
20 m/s2

◦
18 m/s2

◦
13 m/s2

◦
15 m/s2

◦
24 m/s2


Question 2

A particle moves in the xy plane in a circle centered on the origin. At a certain instant the velocity and acceleration of the particle are 6.0 m/s and (3.0 + 4.0) m/s2. What are the x and y coordinates of the particle at this moment?

◦
x = 0, y = −9.0 m

◦
x = 0, y = +7.2 m

◦
x = 0, y = +9.0 m

◦
x = 0, y = −7.2 m

◦
x = 6.0 m, y = −9.0 m
