Primaria Sliding Block

[Xiomy]

The initial velocity of a 1.57 kg block sliding down a frictionless inclined plane is found to be 1.15 m/s. Then 1.02 s later, it has a velocity of 3.93 m/s.



What is the angle of the plane with respect to the horizontal?

[V-V_o]/t=a
a=2.72549m/s^2

a=g*sin @
sin-1(a/g)=@
@=16.13
