Volcanic eruption most likely to happen when the plates are moving intense in the ground. Maybe an earthquake are most likely for a volcanic eruption to occur.
Conservation of momentum requires that the sum of momenta after is equal to that before. Since initially nothing is moving, the sum after the shot will also add to zero.
m₁v₁ = -m₂v₂
Solve for the cannon's velocity v₁
v₁ = -m₂v₂/m₁ = -2.10m/s
The negative sign means it's moving 2.10m/s south.
Answer:
66.85 m
Explanation:
We are given that
Acceleration ,a=
Speed of truck, v=9.5 m/s
We have to find the distance beyond which the traffic signal will the automobile overtake the truck.
Initial speed of automobile, u=0
We know that

Using the formula

For constant speed
Acceleration, a=0
Again



Substitute the value of t

Hence, the distance beyond which the traffic signal will the automobile overtake the truck=66.85 m
