Kinematics Question 628

Question: A projectile of mass m is thrown with a velocity v making an angle 60 with the horizontal. Neglecting air resistance, the change in velocity from the departure A to it’s arrival at B, along the vertical direction is

Options:

A) 2v

B)3v

C) v

D)v3

Show Answer

Answer:

Correct Answer: B

Solution:

[b] At points A and B the vertical component of velocity is vsin60 but their directions are opposite.

Hence, change in velocity. Δv=vsin60(vsin60)=2vsin60=3v
