<span><span>A dragster going at 5 m/s north increases
its velocity to 23 m/s north in 4 seconds. What is its acceleration during this
time interval? In order to calculate the acceleration of the boat we first have
to identify the suited formula for acceleration in this scenario. </span>
<span>Hence, a = vf – vi / t. Vi = 5 m/s Vf = 23 m/s T =
4 seconds </span>
<span>Solution: </span>
<span>A = 23 m/s – 5m/s / 4s </span>
A = 4.5m/s^2 </span>
Answer:
impulse = force * time = 20 * 10 = 200 Ns
change in momentum = impulse = 200 kgm/s
Answer:
ocean wave
Explanation:
ocean waves are not a wavelength but produced from the pull of the moons gravitational pull
