Answer:
12 m/s
Explanation:
a = v² / r
78 m/s² = v² / 2.0 m
v = 12.49 m/s
Rounding to two significant figures, the speed is 12 m/s.

Explanation:
m = mass of burrito thrown by the student = 0.5 kg
a = acceleration of the burrito thrown by the student = 3 m/s²
F = force applied by the student on the burrito = ?
According to newton's second law , the net force on an object is the product of its mass and acceleration. it is given as
F = ma
inserting the values
F = (0.5) (3)
F = 1.5 N
hence the net force on the burrito comes out to be 1.5 N
