F=ma

If force F is reprsented in different, ways then which of the following is correct and which are not correct ? M= mass, a = acceleration r= radius, v= velocity d= distance t=time. (a) F=(mv^(2))/(r), (b) F=ma, (c) F=(ma)/(d) (d) F=ma+(1mv^(2))/(r) (e) F=(md^(2))/(t^(2))

According to Newton s second law of motion F =ma where F is the force required to produce an acceleration a in a body of mass m If a = 0 then F = 0 no external force is required to move a body uniformly along a straight line If a force F acts on a body for t seconds the effect of the force is given by Impulse =F xx t = change in linear momentum of the body The retardation of the ball is .

According to Newton s second law of motion F =ma where F is the force required to produce an acceleration a in a body of mass m If a = 0 then F = 0 no external force is required to move a body uniformly along a straight line If a force F acts on a body for t seconds the effect of the force is given by Impulse =F xx t =change in linear momentum of the body Average force exerted by the bat is .

Chose the correct option The force acting on a body of mass m, produces acceleration a,given by the equation F= ma. If oversetrarrF = (8hati + 6hatj - 10hatk) N and acceleration is 1 m//s^2 , the mass of the body is

According to Newton s second law of motion F =ma where F is the force required to produce an acceleration a in a body of mass m If a = 0 then F = 0 no external force is required to move a body uniformly along a straight line If a force F acts on a body for t seconds the effect of the force is given by Impulse =F xx t = change in linear momentum of the body A cricket ball of mass 150g is moving with a velocity of 12m//s and is hit by a bat so that the ball is turned back with a velocity of 20m//s if duration of contact between the ball and the bat is 0.01sec The impulse of the force is .

Show that in order to get a billiard ball to roll without sliding from the start the cue must hit the ball not at the center (that is, a height above the table equal to the ball's radius R) but exactly at a height 2/5 R above the center [Hint, Consider linear momentum and angular motion of the ball. Apply the condtion for rolling without sliding. F = ma and tau = F xx h = 2/5mR^(2)xx alpha . Condition rolling without a sliding it a =alphaR]
