Answer:
To convert inches to centimeters, use an easy formula and multiply the length by the conversion ratio.
Since one inch is equal to 2.54 centimeters, this is the inches to cm formula to conver
Explanation:
Answer:
3500 joules
Explanation:
Multiply the value by 1000.
Answer:
Explanation:
a ) Applying law of conservation mechanical energy
1/2 mv² = mgh
v =√ 2gh
= √ 2 x 9.8 x 3
= 7.67 m /s
b ) Applying law of conservation of momentum
m x 7.67 = ( m + 2m ) v
= 3m v
v = 2.55 m /s
In perfectly inelastic collision , mechanical energy is not conserved.
Initial kinetic energy
= 1/ 2 x m x v²
= .5 x m x 58.8
= 29.4 m
Kinetic energy after collision
= .5 x 3m x (2.55) ²
= 9.75375 m
Loss of kinetic energy
= 19.646 m
