1) Find the uncertainty in kinetic energy. Kinetic energy
depends on mass and velocity according to this function E(m,v) =
1/2 m v2. Your measured mass and velocity have the
following uncertainties 2.58 kg
and 0.36 m/s. What is is the uncertainty in
energy, , if the measured mass, m = 4.75 kg and the
measured velocity, v = -3.76 m/s? Units are not needed in your
answer

Answer the following questions:
1. An object with mass M and velocity V has kinetic energy K=
1/2MV^2. If the velocity of the object is reduced to 1/5V, then its
new kinetic energy is: a)1/5K b) 5K c)1/25K d) 25K
2. Velocity is a vector, therefore it has magnitude and
direction. In a circular motion, the change in magnitude and
direction of velocity respectively produce: a) centripetal
acceleration and tangential acceleration b) tangential acceleration
and centripetal acceleration c) tangential force...
