Question

A particle of mass 5 kg starts travelling from the origin with a velocity (30î+40j)m/s.if a constant force of (-6î-5j)N is exerted on it, then when the y component of the velocity will be zero?

Answer 1

Answer:

after 40sec

Explanation:

a=-6/5i-j

v=u+at

v=30i+40j+(-6/5i-j)t

so t=40
