A moveing body of 40 kg has 180 joules of KE calculate the speed

1.	A moveing body of 40 kg has 180 joules of KE calculate the speed
Answer» Answer: 3 m/s Explanation: Given, Mass ( m ) = 40 kg Kinetic energy ( K.E ) = 180 J To FIND : SPEED ( v ) = ? K.E = ( m v^2 ) / 2 2 X K.E = m v^2 v^2 = ( 2 K.E ) / m = ( 2 x 180 ) / 40 = 360 / 40 v^2 = 9 v = √9 v = 3 m/s Therefore, the speed is 3 m/s.

Answer»

Answer:

3 m/s

Explanation:

Given,

Mass ( m ) = 40 kg

Kinetic energy ( K.E ) = 180 J

To FIND : SPEED ( v ) = ?

K.E = ( m v^2 ) / 2

2 X K.E = m v^2

v^2 = ( 2 K.E ) / m

= ( 2 x 180 ) / 40

= 360 / 40

v^2 = 9

v = √9

v = 3 m/s

Therefore, the speed is 3 m/s.
