Asystem of inertia 0.47 kg consists of a spring gun attached to a cart and a projectile. the system is at rest on a horizontal low-friction track. a 0.050-kg projectile is loaded into the gun, then launched at an angle of 40∘ with respect to the horizontal plane.

v'=0.83m/a and v=10.2m/s

Explanation:

The information that we have is:

The maximum height of the projectile is given by the equation

So, rearrange for the velocity,

Apply the conservation of momentum,

Then rearrange the recoil speed,

answer; (arch); good luck

weather forecasts are done by collecting data about the current state of the atmosphere mainly the temperature, humidity and wind and using meteorology, to determine the atmosphere that evolves over time. the h and l mean the high and low pressure. the red strip is a warm front. the blue strip is a cold front. the blue and red strip is a stationary front. the purple strip is a occluded front.
