Use the kinematic equation: d = vi • t + ½ • a • t^<span>2
</span><span>20=0(t)+(0.5)(9.8)(t^2)
</span>20=4.9(t^2)
t=2.02seconds
---------------------------------
Final Velocity=Initial Velocity +at^2
Vf=(9.8)(2.02^2)
Vf=19.796
Answer:
No not at all. A car speeding up is an example of acceleration.
Kinetic energy is the energy possessed by an object when in motion. It is calculated by one half the product of the mass and the square of the velocity of the system.
Kinetic Energy = mv^2 / 2 = 50 (10^2) / 2 = 2500 kg m^2/s^2 or 2500 J
Therefore, the correct answer is option E.
Answer: Convergent or Divergent boundaries
Explanation:
Divergent boundaries occur along spreading centers where plates are moving apart and new crust is created by magma pushing up from the mantle. Picture two giant conveyor belts, facing each other but slowly moving in opposite directions as they transport newly formed oceanic crust away from the ridge crest.
Answer:
Explanation:
<u>Given Data:</u>
Momentum = P = 700 kg m/s
Velocity = v = 10 m/s
<u>Required:</u>
Mass = m = ?
<u>Formula:</u>
P = mv
<u>Solution:</u>
m = P / v
m = 700 / 10
m = 70 kg
