Answer:
The new angular velocity will be "80.73 rad/sec".
Explanation:
The given values are:
Angular velocity, W = 20 rad/s
M = 30 N
Time, t = 5 seconds
As we know,
On putting the values in the above formula, we get
Answer:
1
Explanation:
41° 10' N latitude, 74° W longitude
The formula for getting the distance will be distance = speed x time
D = S x T
speed or velocity = 50km/h
time = 0.5 h
the equation will be done directly because it's already in it's SI units
distance = 50km/h x 0.5h
hour cancels hour and the equation remains = 50km x 0.5
Ans = 25 km
the train will move 25 km far in 0.5h
Answer:
The length of the segment AB represents the magnitude of the force.
so its Magnitude of the force
Explanation:
Answer:
The force must he apply to the sled is of F= 764.4 N.
Explanation:
m= 60 kg
g= 9.8 m/s²
μ=0.3
W= m*g
W= 588 N
Fr= μ*W
Fr= 176.4 N
F= W + Fr
F= 764.4 N
