A 2.2 kg pellet is placed in the barrel of a toy gun and is propelled by a spring of force constant 56 N/m. The spring is compressed 2m and then released. Calculate the maximum velocity of the pellet when shot horizontally.

convex lenses are thicker at the middle. rays of light that pass through the lens are brought closer together (they converge). a convex lens is a converging lens. when parallel rays of light pass through a convex lens the refracted rays converge at one point called the principal focus.

a=d/t

a="triangle"v/t

explanation:

a = acceleration

find the sum of the two horizontal vectors and the sum of the two vertical vectors

isoceles right angled triangle
