I believe it’s 1 aka A part of it is reflected as Ray 2
Answer:
8381
Explanation:
Workdone=Force x distance
W= 289x 29
W=8381J
Answer:
1 m/s
Explanation:
Momentum before the collision = momentum after the collision
m₁ u₁ + m₂ u₂ = m₁ v₁ + m₂ v₂
(3000 kg) (2 m/s) + (3000 kg) (0 m/s) = (3000 kg) v + (3000 kg) v
6000 kgm/s = 6000 kg v
v = 1 m/s
Answer:
The power is 29.76 J.
Explanation:
Given that,
Force = 22 N
Radius = 0.28 m
Time = 1.3 s
The force is always applied parallel to the motion of the handle.
So, angle is 0°.
We need to calculate the work done
Using formula of work done
Where, F = force
d = distance
Put the value into the formula
We need to calculate the power
Using formula of power
Hence, The power is 29.76 J.
