A : Due to inertia an object is unable to change by itself its state of rest and uniform motion. R : An object cannot change its state unless acted upon by an unbalanced external force.

Which of the following statements are true? (i) An object will continue moving uniformly until the resultant force on it is zero. (ii) The bodies do not change their state of rest or motion unless acted upon by an unbalanced external force. (iii) If a body is at rest on the surface of the Earth, then the net downward Torce exer force exerted by the Earth and net upward force exerted on the body are not equal to each other.

A car starts moving from rest on a horizontal ground such that the position vector of car with respect to its starting point is given as vec(r) = b t hat(i) - c t^(2) hat(j) , where a and b are position constants, direction (x and y axes) intersect at the starting point of car (origin). Find: (a) The equation of the trajectory of car y = f(x) . (b) The angle between direction of velocity and acceleration of car as a function of time theta = f (t) . (c) Average velocity of car over first t seconds of motion

An object of mass 5 kg is acted upon by a force that varies with position of the object as shown. If the object starts out from rest at a point x=0. What is its speed at x=50 m.

A particle of mass 40 mg and carrying a charge 5 xx 10^(-9) C is moving directly towards a fixed positive point charge on magnitude 10^(-8) C . When it is at a distance of 10 cm from the fixed positive point charge it has a velocity of 50 cm s^(-1) at what distance from the fixed point charge will the particle come momentarily to rest ? Is the acceleration constant during motion?
