Answer:

Step-by-step explanation:

Potential energy at the top of the slide

PE = mgh = 49(9.8)(3) = 1,440.6 J

Energy converted to work of friction

W = Fd = 35(10) = 350 J

Converted potential that becomes kinetic energy

1440.6 - 350 = 1090.6 J

KE = ½mv²

v =
√(2KE/m)

v =
√(2(1090.6)/49)

v = 6.671902...

v = 6.7 m/s
