Given vectors d (3.00 m, 315 degrees wrt x-axis) and e (4.50 m, 53.0 degrees wrt x-axis), find the resultant r= d + e. (a) write r in vector form. (b) write r showing the magnitude and direction in degrees.

(a)

(b) (5.05 m, 16.93 degrees wrt x-axis)

Explanation:

Given:

Let us first fond out vector D and E in their rectangular form.

Similarly,

Part (a):

We can write the resultant vector R as below:

Part (b):

Since both the components of the resultant lie on the positive x and y axes. So, the resultant makes an acute angle with the positive x-axis.

So, R = (5.05 m, 16.93 degrees wrt x-axis)

in simple terms, the principle states that the buoyancy force on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational acceleration, g. this is also known as upthrust.
