Answer:

(a). The horizontal and vertical components are v\cos\theta and v\sin\theta

(b). The horizontal and vertical components of the rocket's impact velocity is 150 m/s and 259.8 m/s.

Explanation:

Given that,

Angle = 60°

Speed = 300 m/s

(a). We need to draw the vector representing the rocket's impact and its components

Using given data

The components of rocket's impact

The horizontal component is

u_{x}=u\cos\theta

The vertical component is

v_{v}=v\sin\theta

(b). We need to calculate the horizontal and vertical components of the rocket's impact velocity

Using horizontal and vertical components

The horizontal component is

v_{x}=v\cos\theta

Put the value into the formula

v_{x}=300\cos60

v_{x}=150\ m/s

The vertical component is

v_{x}=v\sin\theta

Put the value into the formula

v_{x}=300\sin60

v_{x}=259.8\ m/s

Hence, (a). The horizontal and vertical components are v\cos\theta and v\sin\theta

(b). The horizontal and vertical components of the rocket's impact velocity is 150 m/s and 259.8 m/s.

A force of 85 N is used to push a box along the floor a distance of 15 m. How much work was done?
denpristay [2]

Answer:

1275J

Explanation:

Given parameters:

Force on box  = 85N

Distance moved  = 15m

Unknown:

Work done  = ?

Solution:

Work done is the amount of force applied on a body to move it through a specific distance.

 Work done  = Force x distance

Now insert the parameters and solve;

 Work done = 85 x 15  = 1275J
