A banana is launched at a monkey who is 100m above the ground horizontally at a height of 100m, the cannon and and the monkey are 100 meters apart. The monkey falls from the tree as soon as the banana gets launched, if the banana hits the monkey, what is the velocity of the banana?

F500 j of energy were added to 1 kg of each of these samples, which would experience the least temperature increase?

Ablock of mass m = 2.5 kg is attached to a spring with spring constant k = 790 n/m. it is initially at rest on an inclined plane that is at an angle of 28 degrees with respect to the horizontal, and the coefficient of kinetic friction between the block and the plane is k = 0.14. in the initial position, where the spring is compressed by a distance of a = 0.18 m, the mass is at its lowest position and the spring is compressed the maximum amount. take the initial gravitational energy of the block as zero. b) if the spring pushes the block up the incline, what distance, l, in meters will the block travel before coming to rest? the spring remains attached to both the block and the fixed wall throughout its motion.

Find v(t), given acceleration a(t)=7j and initial velocity v(0)=k
