Anyone good at physics, that can help me? Will give 100 point!!!
You don't need to show your work I just need the answer. Thank you.
Starting from rest, a 10 kg block slides 11.9 m down a frictionless ramp (inclined at
30◦ from the floor) to the bottom. The block then slides an additional 21.1 m along the floor before coming to stop. The acceleration of gravity is 9.8 m/s2.
A) Find the speed of the block at the bottom of the ramp.
B)Find the coefficient of kinetic friction between block and floor
C)Find the magnitude of the mechanical energy lost due to friction.

Ahole in the ground in the shape of an inverted cone is 14 meters deep and has radius at the top of 11 meters. the cone is filled to the top with sawdust. the density of the sawdust depends upon the depth, x, following the formula ρ ( x ) = 2.5 + 1.2 e − 0.7 x kg/m3. find the total mass of sawdust in the conical hole.
