Question

I need b & c answer.

**Problem 3:** An object is thrown off the top of a building with a velocity of 32 m/s at an angle of 17° with respect to the horizontal. The object travels a horizontal distance of 280 m before landing on the ground.

**Part (a)** How high is the building in meters?  
**Numeric**: A numeric value is expected and not an expression.  
\( h = \_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_ \)

**Part (b)** What is the magnitude of the velocity of the object when it reaches the ground?  
**Numeric**: A numeric value is expected and not an expression.  
\( v = \_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_ \)

**Part (c)** What is the direction of the object when it reaches the ground, in degrees from the positive x-axis?  
**Numeric**: A numeric value is expected and not an expression.  
\( \theta = \_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_ \)
