A particle is moving with initial velocity `bar(u)=hati-hatj+hatk`. What should be its acceleration so that it can remain moving in the same straight line?

If a particle is moving with a constant velocity, what is its acceleration?

A particle has an initial velocity of 3hati+ 4hatj and an acceleration of 0.4hati +0.3hatj Its speed after 10 s is

A particle has an initial velocity 3hati+3hatj and acceleration of 0.41hati+0.3hatj . Its speed after 10s is

A particle at origin (0,0) moving with initial velocity u = 5 m/s hatj and acceleration 10 hati + 4 hatj . After t time it reaches at position (20,y) then find t & y

A particle at origin (0,0) moving with initial velocity u = 5 m/s hatj and acceleration 10 hati + 4 hatj . After t time it reaches at position (20,y) then find t & y

A particle has an initial velocity of 4 hati +3 hatj and an acceleration of 0.4 hati + 0.3 hatj . Its speed after 10s is
