Apole-vaulter first converts kinetic energy into. a.. thermal energy.. b.. chemical energy.. c.. mechanical energy.. d.. elastic potential energy..

option d: elastic potential energy.

Explanation:

We know that energy possessed by a body due to virtue of its motion is known as kinetic energy and due to virtue of its position is known as potential energy.

A pole vaulter uses a long flexible pole as an aid for jumping over a bar. A pole vaulter gathers kinetic energy by sprinting down on runway and then lifts off and jumps using the pole to cross the bar. In this step, the pole vaulter converts kinetic energy into elastic potential energy.

which three statements are true about all alloys?

we're given that v₀ = 0 and a = 5.4 m/s². therefore, since v = at + v₀ for constant acceleration the equation for velocity is

after 28s,

m/s

which i would round to 150 m/s as my final answer
