Question

a truck weighing 200 kg is moving with an energy of 16 multiply 10 raised to power 5 find tje velocity.

Answer 1

0.5*Mass*velocity ^2 = 1600000
0.5*200*v^2 = 1600000
v^2 = (1600000)/100
v^2 = 16000
v = 126.5

Answer 2

Given ;
m = 200 kg
K.E = 16 × 10^5 J
v = ?

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

16×10^5 = (1/2)×200×v^2
v^2 = 16×10^3
v = 4×10√10

v = 40√10 m/s
