The distance the ball rolls is given by

<em>x</em> = 1/2 <em>a</em> <em>t</em>²

so that

<em>x</em> = 1/2 * (3.3 m/s²) * (7.5 s)² = 92.8125 m ≈ 93 m

1-D catch-up: Two cars move with constant velocities. At t = 0, a blue car is at xBo = 20 m. After t = 4s in the blue car time f
OlgaM077 [116]

Answer:

5.71 m/s ;

20 m/s

Explanation:

Blue car:

At time, t = 0 ; Initial position = 20 m

Final position, = 60m after 4 seconds

The velocity = change in distance / change in time.

Velocity of blue = (60 - 20)m ÷ ((4 + 3) - 0),

Velocity of blue car = 40 / 7

= 5.71 m/s

Red car:

Initial Position = 0 ; final Position = 60

Time taken = 3 seconds

Velocity of Red car = (60 - 0)m ÷ 3

Velocity of Red car = 60 / 3

= 20 m/s
