Answer:
t = 0.2845Nm (rounded to 4 decimal places)
Explanation:
The disk rotates at a distance of an arc length of 28cm
Arc length = radius × central angle × π/180
28cm = 10cm × central angle × π/180
Central angle = × 180/π ≈ 160.4°
Torque (t) = rFsin(central angle) , where F is the applied force
Radius in meters = 10/100 = 0.1m
t = 0.1m × 16N × sin160.4°
t = 0.2845Nm (rounded to 4 decimal places)
Answer:
15.03 m
Explanation:
Given:
mass of the block, m = 7.25 kg
Angle, Θ = 28.5°
Initial speed of the block, v₀ = 15 m/s
let the distance traveled by the block be 's'
Now, applying the work energy theorem,
we have
on substituting the values in the above equation, we get
or
or
s = 15.03 m
Hence, the block will travel 15.03 m up the ramp
