The object is moving with constant speed means there is no change in speed Hence the acceleration is 0
Where, u is initial speed,
v is final speed
t is time taken and
a is acceleration
a = ( v-u) /t
a =(0)/t because u=v
a=0
Therefore, Acceleration is 0
Explanation:
The runner runs for a total time of
\Delta t=10.0 min= 600 sΔt=10.0min=600s
The energy converted by the runner during this time is equal to the power of the runner times the total time:
E=P \Delta t=400 W \cdot 600 s =2.4 \cdot 10^5 JE=PΔt=400W⋅600s=2.4⋅10

Answer: 39.2m/s
Explanation:
Due to the free falling body, the acceleration of the ball is 9.8 m/s^2, and its initial velocity is 0 m/s.
V(t) = g*t
The change of velocity from t=1 to t=5:
Delta V = 9.8*(5-1) = 39.2 m/s
Answer:
I had this on my test too it took a lot of thinking but I got it
Explanation:
Energy is not created but transformed meaning the energy just transformed into a different type meaning at all points of the ramp the energy stays the same because all of its energy is just transformed into kinetic energy.
