A ball is thrown vertically upward with a velocity of 19.6 metre per second and momentarily come to rest in how much time?.... |
|
Answer» tion:Given that,Initial velocity u=19.6m/sFinal velocity v=0Time t=6secThe acceleration isWe know that, v=u+at 0=19.6+a×6 a=−3.26m/s 2 Now, the height isFrom EQUATION of motion s=ut+ 21 at 2 s=19.6×6− 21 ×3.26×36 s=58.9 s=59mHence, the height of the tower is 59 MTHE work–energy theorem: - The work done by all forces on an object is equal to the change in kinetic energy of the object. W=ΔkFrom newton second LAW,F=ma....(I)We know that,a= dtdv So, put the value of a in equation (I)F=m dtdv If multiple both SIDE by vF.v=mv dtdv .....(II)We know that,v= dtdx Now, put the value of v in equation (II)F dtdx =mv dtdv Now, on integrating Fdx=mvdv F 0∫x dx=m v 1 ∫v 2 vdv Fx= 21 m(v 22 −v 12 ) Fx= 21 mv 22 − 21 mv 12 We know that, W=Fx 21 mv 2 =kk = kinetic energyNow, W=k 2 −k 1 W=ΔkThe work –energy theorem is proved. |

when two forces act on a body in opposite direction along strike line one of the force should be the another to change the state of motion of your body |
|
Answer» Here we apply two FORCES of same MAGNITUDE but OPPOSITE in direction.Hence we have F and - F which makes resultant force as zero.Moment of force for F is R×F. For force F it has distance r therefore it has moment rF and same with force -F.Hence moment of force is rF.The forces tend to rotate the body about the mid-point between the two forces.I hope it will be helpful to you FRIEND |
