Answer:
the magnitude of the net force acting on the kayak is 14.77 N.
Step-by-step explanation:
Given;
initial velocity of the kayak, u = 0
final velocity of the kayak, v = 0.509 m/s
distance traveled by the kayak, d = 0.555 m
combined mass of the person and kayak, m = 63.4 kg
Determine the acceleration of the kayak by using the following kinematic equation;
v² = u² + 2ad
(0.509)² = 0 + (2 x 0.555)a
0.259081 = 1.11a
a = 0.259081 / 1.11
a = 0.233 m/s²
The magnitude of the net force acting on the kayak is calculated by using Newton's second law of motion;
F = ma
F = 63.4 x 0.233
F = 14.77 N
Therefore, the magnitude of the net force acting on the kayak is 14.77 N.
