Questions
A particle of mass 2kgmoves with an initial velocity of on the x-y plane. A force acts on the particle. The initial position of the particle is (2 m,3 m). Then for y=3 m,
detailed solution
Correct option is B
u→=4i^+2j^, a→=F→m=i^−4j^Let at any time, the coordinates be (x, y)x−2=uxt+12axt2⇒x−2=4t+12t2 and y−3=2t−124t2⇒y−3=2t−2t2 When y=3m,t=0,1s; when t=0,x=2m When t=1s,x=6.5mTalk to our academic expert!
