Adart leaves a toy dart gun with initial velocity of 7.76 m/s, regardless of the angle it is fired. what is the maximum horizontal distance that the dart can travel? assume that the dart gun is fired at ground level.

An object has a weight of 500 on earth what is the mass of this object

The slope of a velocity time graph over any interval of time gives the during that interval

Consider a 1000 w iron whose base plate is made of 0.5 cm thick aluminum alloy 2024-t6 (ρ = 2770 kg/m3 and cp = 875 j/kg°c). the base plate has a surface area of 0.03 m2. initially, the iron is in thermal equilibrium with the ambient air at 22°c. assuming 90% of the heat generated in the resistance wires is transferred to the plate, determine the minimum time needed for the plate temperature to reach 200°c.
