Answer:given below by him is correct
Explanation:
Pls refer his
Answer:
11 m/s south
Explanation:
The velocity of the passenger relative to the river bank is equal to the velocity of the passenger relative to the ferry, plus the velocity of the ferry relative to the river, plus the velocity of the river relative to the river bank.
v_passenger,bank = v_passenger,ferry + v_ferry,river + v_river,bank
If we take north to be positive and south to be negative:
v = 1.0 m/s + (-10 m/s) + (-2 m/s)
v = -11 m/s
v = 11 m/s south
Answer:
Explanation:
As we know that the angular acceleration of the wheel due to friction is constant
so we can use kinematics
so we have
now time required to completely stop the wheel is given as
now time required to stop the wheel is given as
