Answer: 90m
Explanation:
Use Equation for distance:
S=a*t²/2
use eqation for acceleraton a=(Vf-Vs)/t
Vs- starting speed
Vf - final speed
a-accelaration
---------------------------------
a=5m/s²
Vs=0m/s
Vf=30m/s
use
a=(Vf-Vs)/t
to find time
t=(Vf-Vs)/a
t=30m/s/5m/s²
t=6s
Now calculate distance that object travel using:
S=(a*t²)72
s=(5m/s²*(6s)²)/2
S=90m
Answer:
m/s^2
Explanation:
Force = mass × acceleration
kgm/s^2 = kg × acceleration
where acceleration = Force ÷ mass
= kg m/s^2 ÷ kg
:Acceleration = m/s^2
Answer:
K = m g (h₀ - h_plat)
Explanation:
Let's use energy conservation to solve this problem, write the energy at two points of interest
Initial. Higher
E_initial = m g h₀
Final. Lower
E_end = K + Ep
E_end = ½ m v² + m g h_plat
Energy is conserved
E_initial = E_end
m g h₀ = K + m g h_plat
K = m g (h₀ - h_plat)
Answer:
Change its velocity by 10 m/s in 1s
Explanation:
Answer:
21m/s east is the resultant velocity
Explanation:
I got this answer as 33 - 12 = 21
