While running a 100m race, a runner runs from the 20m to 30m mark in 77 frames of a video record. If the video camera recorded d
Marrrta [24]

Answer:

Speed of the runner during video interval is 6.49 m/s

Explanation:

According to the problem,

Number of frames recorded by camera in 1 second = 50

Time takes by camera to record 1 frame = (1/50) s

Time taken by camera to record 77 frames, t = \frac{1}{50}\times 77 s

Distance covered by the runner during the video recording, d = 10 m

Speed, v = \frac{Distance}{time}=\frac{d}{t}

Substitute the values of d and t in the above equation.

v = \frac{10}{\frac{77}{50} }

v = 6.49 m/s

A 10 kg box hangs from a rope. What is the tension in the rope (in Newtons) if the box is stationary
Archy [21]

Answer:

T = 98 N

Explanation:

The gravity of the earth is known to be 9.8 m/s²

Data:

  • m = 10 kg
  • g = 9.8 m/s²
  • T = ?

Use formula:

  • \boxed{\bold{T=m*g}}

Replace and solve:

  • \boxed{\bold{T=10\ kg*9.8\frac{m}{s^{2}}}}
  • \boxed{\boxed{\bold{T=98\ N}}}

The tension in the rope is <u>98 Newtons.</u>

Greetings.
