At time t seconds , the force F newtons acting on particle P, of mass 0.5 KG , is given by
F= ( 3t ) i + (4t-5)j .
When t=1 , the velocity of P is 12 i m/s
Find velocity of P after t seconds
The angle the direction of motion of p makes with i when t=5 .
also i woudl like to know , when the question says for example
Find t when v is paraller to i . This means j = 0
but when he says i+j or i-j , what does this mean?
Gradient = 1 and gradient = -1
