The roof of a two-story house makes an angle of 29° with the horizontal. A ball rolling down the roof rolls off the edge at a sp

Answer:

$t = 0.93 s$

Part b)

$d = 3.98 m$

Part c)

$v_x = 4.28 m/s$

$v_y = -11.49 m/s$

Explanation:

The two components of the velocity of the ball is given as

$v_x = 4.9 cos29$

$v_x = 4.28 m/s$

$v_y = 4.9 sin29$

$v_y = 2.37 m/s$

Part a)

now we know that the displacement in y direction is given as

$\Delta y = 6.4 m$

so we have

$\Delta y = v_y t + \frac{1}{2}gt^2$

$6.4 = 2.37 t + 4.9 t^2$

$t = 0.93 s$

Part b)

Distance of the ball in x direction of the motion is given as

$d = v_x t$

$d = 4.28 \times 0.93$

$d = 3.98 m$

Part c)

In x direction the velocity will remain the same always

$v_x = 4.28 m/s$

while in Y direction we can use kinematics

$v_y = v_{oy} + at$

$v_y = -2.37 - 9.81(0.93)$

$v_y = -11.49 m/s$
