Answer #1
( a) . Area under the curve and time axis gives impulseof the force( b ) . we know impulse = m ( v - u )where u = initial velocity = 0 m / sm = mass = 2.3 kgfrom this we find final velocity of theballi.e., v value( c ) . put u = - 1 m / sin above equation we get answer

    Learning Goal: To understand the relationship between force, impulse, and momentum. The effect of a net force ΣF⃗ acting on an object is related both to the force and to the total time the force acts on the object. The physical quantity impulse J⃗ is a measure of both these effects. For a constant net force, the impulse is given by J⃗ =F⃗ Δt. The impulse is a vector pointing in the same direction as the force vector. The units...
