The final velocity will be 19 m/sec.Option C is correct.
<h3>What is velocity?</h3>The change of displacement with respect to time is defined as the velocity.
Velocity is a vector quantity. it is a time-based component. Velocity at any angle is resolved to get its component of x and y-direction.
From Newton's first equation of motion;
The final velocity will be 19 m/sec
Hence, option C is correct.

Answer:
w = -0.475N
Explanation:
To get Va and Vb
R = 0.525 m
m = 0.0350 kg
g = 9.8 m/s²
K.Ea = 0.5 * 0.035 * 7.25²
K.Ea = 0.92 J
Since point A is at the bottom of the path, h = 0 m
P.Ea = 0 m
For Vb
Answer
given,
mass of bowling ball = 7.25 Kg
moving speed of the bowling ball = 9.85 m/s
mass of bowling in = 0.875 Kg
scattered at an angle = θ = 21.5°
speed after the collision = 10.5 m/s
angle of the bowling ball
b) magnitude of final velocity
v = 8.68 m/s
