Question

60o is equal to how many radians?

pi / 3

pi / 4

2pi / 3

2pi / 7

If an object's mass decreases, its momentum will ________.

Increase

Decrease

Remain the same

None of the above

Answer 1

(1)θr = θ° * π /180 = 60 * π /180 = π / 3

(2)Decrease because momentum = mass * velocity that means that momentum is proportional to mass If mass decreases momentum will decrease too.
