Answer:
the rocks have the same amount of thermal energy
Answer:
Explanation:
If the dragster attains the speed equal to that of the car which is moving with constant velocity of v₀ , before the two close in contact with each othe , there will not be collision .
So the dragster starting from rest , must attain the velocity v₀ in the maximum time given that is tmax .
v = u + a t
v₀ = 0 + a tmax
tmax = v₀ / a
The value of tmax is v₀ / a .
Answer:
h = 16.67m
Explanation:
If the kinetic energy of the cylinder is 510J:
Where the inertia is given by:
Replacing this value:
Speed of the block will therefore be:
By conservation of energy:
Eo = Ef
Eo = 0
So,
Solving for h we get:
h=16.67m
