Solution
To find the speed of the jaguar, we can use the formula for kinetic energy, which is KE = 1/2 * m * v^2, where KE is kinetic energy, m is mass, and v is velocity (or speed).
Given that the kinetic energy (KE) is 146 Joules and the mass (m) is 70 kg, we can rearrange the formula to solve for v:
v = sqrt((2*KE)/m)
Substituting the given values:
v = sqrt((2*146 J)/70 kg)
v = sqrt((292 J)/70 kg)
v = sqrt(4.17142857143 kg*m^2/s^2)
v = 2.04 m/s
So, the jaguar is moving at a speed of 2.04 m/s.
