Impulse exerted by the ball on the wall</h3>
The impulse exerted by the ball on the wall is the change in the linear momentum of the ball.
J = ΔP
ΔP = Pf - Pi
P = mv
where;
- m is mass of the ball
- v is the velocity
ΔP = 3(4.0i + 3.0j) - 3(-4.0i + 3.0j)
ΔP = (12i + 9j) - (-12i - 9j)
ΔP = 24i kgm/s
Thus, the impulse exerted on the ball by the wall is 24i kgm/s.

Transverse waves are always characterized by particle motion being perpendicular to wave motion. A longitudinal wave is a wave in which particles of the medium move in a direction parallel to the direction which the wave moves.
Answer:
-18.1 cm and upright
Explanation:
u = Object distance = 25 cm
v = Image distance = -10.5 cm
f = Focal length
Lens Equation
Focal length of the lens is -18.1 cm
Magnification
Since magnification is positive the image upright
