A canon shell moving along a straight line bursts into two parts. Just after the burst one part moves with momentum 20 N s making an angle 30^(@) with the original line of motion. The minimum momentum of the other part of shell just after the burst is

if a=3t^(2)+2t , initial velocity is 5 m//s . Find the velocity at t=4s. The motion is in straight line, a is acceleration in m//s^(2) and t is time in seconds.

The initial velocity of a body moving along a straight lines is 7m//s . It has a uniform acceleration of 4 m//s^(2) the distance covered by the body in the 5^(th) second of its motion is-

Find the equation of the straight line which has y-intercept equal to 4/3 and is perpendicular to 3x-4y+11=0

A particle is moving in a straight line according as s=45t+11t^2-t^3 then the time when it come to rest is

A partical is moving in a straight line under constant acceletation. If the motion starts from rest, Find the ratio of displacement in n second to that in the n^(th) second.

A free body of mass 8 kg is travelling at 2 mater per second in a straight line. At a certain instant , the body splits into two equal parts due to internal wxplosion which releases 16 joules of energy . Neither part leves the original line of motion. Finally

Fig. 2 (NCT). 6 shows x-t plot of one dismensional motion a particle. Is it correct to say from the graph that the particle moves in a straight line for t lt 0 and on a parabolic path form t gt 0 ? If not, suggest a suitable physical contxt for this graph.
