Answer:
independent of the projectiles mass
Explanation:
the range only depends on velocity of projection,angle of projection,acceleration due to gravity.
Answer:
<h3>The answer is 5 g/mL</h3>
Explanation:
The density of a substance can be found by using the formula
From the question
mass = 150 g
volume = 30 mL
We have
We have the final answer as
<h3>5 g/mL</h3>
Hope this helps you
Answer:
It will be more spread out
Explanation:
As you increase the height, the gravitational potential energy increases and it gets faster, causing it to hit the ground harder. This in turn makes the 'splat' be more spread out
Answer:
Explanation:
Mass of first cart M1=2.4kg
Velocity of first cart U1=4.1m/s
Mass of second cart M2=1.7kg
Second cart is initially at rest U2=0
After an instant, the velocity of the second cart is U2=-2.8m/s
Now after collision the two cart move together with the same velocity I.e inelastic collision
Using conservation of momentum
Momentum before collision, = momentum after collision
M1U1 + M2U2 = (M1+M2)V
2.4×4.1 + 1.7× -2.8 =(2.4+1.7)V
9.84 - 4.76 = 4.1V
5.08=4.1V
V=5.08/4.1
V=1.24m/s
The momentum of the two cart at that instant is
M1U1+M2U2
2.4×4.1 + 1.7× -2.8
9.84 - 4.76
5.08kgm/s
So the momentum at the instant the velocity is 4.1m/s for cart 1 and -2.8m/s for cart 2 is 5.08kgm/s
