I do not get part D?
An object with mass 0.200 kg is acted on by an elastic restoring force with force constant 10.8 N/m. The object is set into oscillation with an initial potential energy of 0.150 J and an initial kinetic energy of 7.00 times10^-2 J. Significant Figures Feedback: Your answer 0.142 m was either rounded differently or used a different number of significant figures than required for this part. What is the value of the phase angle...

With the given information, it is impossible to choose between
the positive and negative solutions in part (b). Notice that the
sum KE +
in part (c) equals the total energy E found in part (a), as it
should (except for a small discrepancy due to rounding).

A ball of mass m moving with velocity v_i_vec strikes a vertical
wall. The angle between the ball's initial velocity vector and the
wall is theta_i as shown on the diagram, which depicts the
situation as seen from above. The duration of the collision between
the ball and the wall is Deltat, and this collision is completely
elastic. Friction is negligible, so the ball does not start
spinning. In this idealized collision, the force exerted on the
ball by the...

Explore A baseball is thrown from the top of a tall building with an initial velocity of 10 m/s from a height of h= 11.5 m above the ground. Find its speed when it reaches the ground (a) if its launch angle is 37°, and (b) if it is launched horizontally. Conceptualize As the baseball moves upward and to the right, the force of gravity accelerates it downward. The vertical component of its velocity decreases in magnitude until the baseball...

A 1-kg ball in the air has an initial velocity vo = [ 10 ] i + [ -20 ] j m/s. It falls for a total time of 1 s. Assume that positive x-values are to the right and positive y-values are upward. What is the initial kinetic energy Ki of the ball? J Remember that the initial kinetic energy Ki = pi2/2m. To find the magnitude of the resultant momentum we must use the pythagorean theorem on the...
