Answer:
When a patient has a chipped tooth, it means that a small portion of their tooth is no longer there. Chipped teeth are one of the more common types of dental problems that general dentists deal with. However, chipped teeth do not grow back on any portion of a tooth and instead need to be repaired by a general dentist.

Answer:
The initial velocity of the ball is 28.714 m/s
Explanation:
Given;
time of flight of the ball, t = 2.93 s
acceleration due to gravity, g = 9.8 m/s²
initial velocity of the ball, u = ?
The initial velocity of the ball is given by;
v = u + (-g)t
where;
v is the final speed of the ball at the given time, = 0
g is negative because of upward motion
0 = u -gt
u = gt
u = (9.8 x 2.93)
u = 28.714 m/s
Therefore, the initial velocity of the ball is 28.714 m/s
Answer:
the force exerted by the seat on the pilot is 10766.7 N
Explanation:
The computation of the force exerted by the seat on the pilot is as follows:

Hence, the force exerted by the seat on the pilot is 10766.7 N
F=ma therefore 25kg*1.0m/s^2=25N force on the mass
