A baseball rolls off a 1.20 m high desk and strikes the floor 0.50m away from the base of the desk. how fast was the ball rolling?

1.01 m/s

Step-by-step explanation:

a = g = Acceleration due to gravity =

t = Time

= Displacement in y direction = 1.2 m

= Displacement in x direction = 0.5 m

= Velocity in x direction

Displacement in y direction is given by

The ball was rolling with a speed of 1.01 m/s.

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.

1/4 is the answer if i recall correctly.
