Hi sir here with problem if you are free pls provide solution for this



1) An object is thrown upward with a speed of 25ms-1.How high will it be when the speed is 12ms-1 ?
A) S=ut + 1/2 at^2
B) S= (u+v)t/2
C) V=u+ at
D) V^2=U^2+2aS

Which equation will allow the problem to be solved in a single calculation?

a block is plased on an inclined plane of angle of inclination 37 degree to the horizontal. if the coefficient of friction between the block and the plane is 0.25.calculate the acceleration of block?
