Q) 20. Calculate the velocity of a 35 kg bike with a kinatic energy of 158 2m/s 9m/s 3m/s 1575m/s

To calculate the velocity of the bike, we can use the formula for kinetic energy:<br /><br />Kinetic Energy = (1/2) * mass * velocity^2<br /><br />Given:<br />- Kinetic Energy = 158 J<br />- Mass = 35 kg<br /><br />We need to solve for velocity.<br /><br />Rearranging the formula, we get:<br /><br />Velocity = sqrt((2 * Kinetic Energy) / mass)<br /><br />Plugging in the values:<br /><br />Velocity = sqrt((2 * 158 J) / 35 kg)<br />Velocity = sqrt(316 J / 35 kg)<br />Velocity = sqrt(9.02857 m^2/s^2)<br />Velocity ≈ 3 m/s<br /><br />Therefore, the velocity of the bike is approximately 3 m/s.
