The solution for the problem is:
Constant speed means Fnet = 0.
Let m = mass of wood block and Θ = angle of ramp; then if µk = 0.35 …
The computation would be:
Fnet = 0 = mg (sin Θ) - (µk) (mg) (cos Θ)
mg (sin Θ) = µk (mg) (cos Θ)
µk = tan Θ
Θ = arctan(µk)
= arctan (0.35)
≈ 19.3°
Answer:
7)
8)
9)
10)
Explanation:
For the problems 7, 8 and 9 we just apply the definition of acceleration, since no more information is given, which is:
So for each problem we will have:
7)
8)
9)
For the problem 10, we use the equation of velocity in accelerated motion:
Since the ball starts from rest and the acceleration is that of gravity (we take the downward direction positive), we have:
Answer:110v
Explanation:
Current=100 amperes
Resistance=1.1 ohms
voltage=current x resistance
Voltage=100 x 1.1
Voltage=110v
