a dog runs back and forth between its two owners, who are walking toward one another. the dog starts running when the owners are

alexandr402 [8]

Answer:

11.54 meters

Explanation:

The owners take 10m / (1.3 + 1.3 m/s) = 3.85 seconds to meet

The dog is running at constant speed of 3 m/s for these 3.85 seconds

3 m/s * 3.85 sec = 11.54 meters

6. A skier starts from rest at the top of a frictionless incline of height 20.0 m. At

n200080 [17]

Explanation:

a. KE at bottom = PE at top

½ mv² = mgh

v = √(2gh)

v = √(2 × 9.8 m/s² × 20.0 m)

v = 19.8 m/s

b. Work by friction = PE at top

mgμ d = mgh

d = h / μ

d = 20.0 m / 0.210

d = 95.2 m

A remote-controlled car's wheel accelerates at 22.6 rad/s2 . If the wheel begins with an angular speed of 10.2 rad/s, what is th

Lapatulllka [165]

Answer:

70.9pi rad/s

Explanation:

angle turned through = 16

angular acceleration = 22.6 rad/s2

angular speed = 10.2 rad/s

time = ?

angular acceleration = angular speed/time

time = 10.2/22.6

time = 0.45 seconds

angular speed = angle turned through/time

angular speed = (16 × 2pi)/0.45

= 70.9pi rad/s
