Question

how fast should a man of mass 60 kg Run so that his kinetic energy is 750 Joule ​

Answer 1

Answer:

Explanation:

Given ;

Mass = 60 kg

K.E = 750 J

v = ?

K.E = (1/2)mv^2

750 = (1/2) × 60 × v^2

v^2 = 150/6

v = √25

v = 5 m/s

____________________

Hence the man should run with a velocity of 5m/s

Answer 2

• Mass = 60 kg

• K.E = 750 J

• v = ?

→ K.E = (1/2)mv²

⇒ 750 = (1/2) × 60 × v²

⇒ v² = 150/6

⇒ v = √25

⇒ v = 5 m/s

∴  The man should run with a velocity of 5m/s
