A diver, of mass 40kg, climbs up to a diving platform 1.25m high. What’s her KE
1 answer:
Explanation:
The formula for KE ( Kinetic Energy ) is : 1/2 mv²
Solution:
- First we solve for v ( velocity ) using the formula 2gh, where g is gravity [ 9.8 m/s² ] and h is height [ 1.25 m ]
= 2 ( 9.8 m/s² × 1.25 m ) = 24.5 m/s
- The velocity is 24.5 m/s.
- Now solve for KE using the formula 1/2 mv²
= 1/2 ( 40 kg × 24.5m/s ² )
= 1/2 ( 40 kg × 600.25 )
= 1/2 ( 24,010 )
= 12,005 Joules
- The diver's kinetic energy is 12,005 J.

They do not react with or chemically bond to each other.
F = kq1q2/r²
F = 9.0(10^9)(10)(50)/20²
F = 1.125 * 10^10 N
False because currents do not flow easily through insulators. If it only said conductors, then it would be true.
