A projectile is fired at time t = 0.0 s, from point 0 at the edge of a cliff, with initial velocity components of vox = 50 m/s and voy =200 m/s. The projectile rises, then falls into the sea at point P. The time of flight of the projectile is 50.0 s. The y-coordinate of the projectile when its x-coordinate is 1000 m is closest to:. A) 1240 m
B) 150 m
C) 150 m
D) 2040 m
E) 600 m

Which is an example of an exothermic process?

Why does the equilibrium position of the spring change when a mass is added to the spring? will the mass oscillate around the new equilibrium position of the spring or the previous position without a mass attached to the spring? if the equilibrium position of the spring changes by 20 cm (assuming no initial mass) when a mass is added to the spring with constant 4.9 kg/s^2, what is the mass of the object attached to the spring?

If 0.05j work is done by stirring a cup of tea, if 150ml of tea is stirred 50 times and temperature rises to 67c° what will be the increase in entropy? a)0.007j/k b)1.1j/k
