Given:
u= 0.91 m/s
a=0.31m/s∧2
s= 0.61 m
s = ut +1/2(at∧2)
where s is the displacement of the object
u is the initial velocity
t is the time
a is the acceleration
Substituting the values
0.61=0.91×t +(0.31 ×t∧2)/2
0.61=0.91 t + 0.155 t∧2
t=0.61 secs
Consider the equation
<u>v=u +at
</u>
where v is the initial velocity
u is the initial velocity
a is the acceleration
t is the time
Substituting the values we get
v= 0.91 +(0.31×0.61)
v= 1.099 m/s
Answer:
Explanation:
An inelastic collision is one in which the internal kinetic energy changes (it is not conserved) . The two objects come to rest after sticking together, conserving momentum. But the internal kinetic energy is zero after the collision.
The star that would be hotter would be; the star emitting visible light.
Answer:
Five Characteristics of a Mineral
Minerals Are Natural. You must find minerals in nature; substances concocted in laboratories don't qualify. ...
Minerals Are Inorganic. ...
Minerals Are Solids. ...
Definite Chemical Composition. ...
Crystalline Structure.
These are just some examples.
Explanation:
M = 150 kg.
Final velocity, v = 14 m/s
Initial Velocity, u = 6 m/s
Impulse = <span> m(v - u)</span>
= 150*(14 - 6)
= 150*8 = 1200 kgm/s or 1200 Ns<span> </span>
