Answer: 600 m

Explanation:

Speed V is defined as the distance traveled d in a especific time t:  

V=\frac{d}{t}  

Where:  

V=343 m/s \approx 300 m/s is the speed of sound  

t=2 s the time you hear the thunder after you see the flash of lightning  

We need to find the distance at which you are from the lightning strike:  

300 m/s=\frac{d}{2 s}  

Finding d:  

d=(300 m/s)(2 s)  

Finally:  

d=600 m

evablogger [386]

Given the time, the final velocity and the acceleration, we can calculate the initial velocity using the kinematic equation A:

v = v_o + a \Delta t

A skateboarder flies horizontally off a cement planter. After a time of 3 seconds (Δt), he lands with a final velocity (v) of −4.5 m/s. Assuming the acceleration is -9.8 m/s² (a), we can calculate the initial velocity of the skateboarder (v₀) using the kinematic equation A.

v = v_o + a \Delta t\\\\v_o = v - a \Delta t = (-4.5 m/s) - (-9.8 m/s^{2} ) \times 3 s = 24.9 m/s

Given the time, the final velocity and the acceleration, we can calculate the initial velocity using the kinematic equation A:

v = v_o + a \Delta t
