A ball traveling 25 m/sec is struck by an implement (moving in the opposite direction) with enough force to accelerate 2 the ball at a rate of 130 m/sec . Calculate final velocity if the implement and the ball made contact for 0.5 sec.

Explanation:

Given

initial velocity of the ball u = 25m/s

acceleration a = 130m/s²

time t = 0.5secs

Required

Final velocity v

Using the equation of motion

v = u+at

Substitute the given values

v = 25 + 130(0.5)

v = 25 + 65

v = 90

Hence the final velocity if the implement and the ball made contact for 0.5 sec is 90m/s

explanation:

earth's surface is mainly heated by the absorption of infrared radiation from the sun.

evaporation occurs because molecules in liquid water are warmed ( usually by the sun) and vibrate quicker, becoming less dense and rise.

condensation occurs because molecules in water vapor are cooled and therefore vibrate more slowly thus becoming more dense and eventually fall to earth.

lines of equal barometric pressure on a weather map are called: isobars : lines of equal temp on a weather map are called: isotherms.​

the answer is kevlar
