The impulse-momentum theorem states that the change in momentum of an object equals the impulse applied to it.
Thus, change in momentm= Impulse=F.t
=F0.(1/2T)
=F0T/2

A racquet ball with mass m = 0.252 kg is moving toward the wall
at v = 18.2 m/s and at an angle of θ = 25° with respect to the
horizontal. The ball makes a perfectly elastic collision with the
solid, frictionless wall and rebounds at the same angle with
respect to the horizontal. The ball is in contact with the wall for
t = 0.06 s.

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...

Tug the macaroni penguin throws a frozen 12.00 g krill
toward a
vertical wall. The frozen krill strikes the vertical wall traveling
with a
speed of 8.00 m/s. The frozen krill rebounds off of the wall
horizontally
and the force that the wall exerts on the krill during the time of
contact
is shown in the graph (rightwards is the positive direction).
a. Calculate the impulse imparted on the frozen krill.
b. Find the equivalent average force exerted on the...

A billiard ball strikes and rebounds from the cushion of a pool table perpendicularly. The mass of the ball is 0.38 kg. The ball approaches the cushion with a velocity of +2.50 m/s and rebounds with a velocity of -1.80 m/s. The ball remains in contact with the cushion for a time of 3.00 × 10-3 s. What is the average net force (magnitude and direction) exerted on the ball by the cushion? F =...... (number) ....... the tolerance is...

A ball of mass m moving with velocity v⃗ i strikes a vertical wall as shown in (Figure 1) . The angle between the ball's initial velocity vector and the wall is θi 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 Δt, and this collision is completely elastic. Friction is negligible, so the ball does not start spinning. In this idealized collision, the...
