A concrete slab of mass 400 kg accelerates down a concrete slope inclined at 35°. The kinetic between the slab and slope is 0.60
. Determine the acceleration of the block.
1 answer:
I got you
Explanation:
normal force = 400 g cos 35
friction force up slope = .6 (400 g) cos 35
weight component down slope = 400 g sin 35
400 a = 400 g sin 35 - .6 (400 g cos 35)
a = g (sin 35 - .6 cos 35) = .082 g

Answer:
The answer is D
The second law of thermodynamics
Since the initial velocity is 30 and the final is 0. 15 is the vave so you can use that with 1/2mv^2 to find the force
30 is the correct answer your looking for
