Ariver flows due east at 2.33 m/s. a boat crosses the river from the south shore to the north shore by maintaining a constant velocity of 9.76 m/s due north relative to the water. the river is 212 m wide. what is the velocity of the boat relative to shore? answer in units of m/s.

V = 10.03 m/s

Explanation:

It is given that,

Velocity of the river, v₁ = 2.33 m/s

Velocity of the boat, v₂ = 9.76 m/s

Width of the river, d = 212 m

Let v is the velocity of the boat relative to the shore. It can be calculated using vector sum as :

v = 10.03 m/s

So, the velocity of the boat relative to shore is 10.03 m/s. Hence, this is the required solution.

explanation:

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards
