Answer:
V = 0.074 m/s
Explanation:
given,
mass of the receiver, M = 96 Kg
mass of the ball, m = 0.42 Kg
initial speed of the ball, v = 17 m/s
initial speed of the receiver = 0 m/s
final speed.V = ?
using conservation of momentum
M u + m v = (M + m) V
0 + 0.42 x 17 = (96+0.42) V
96.42 V = 7.14
V = 0.074 m/s
hence, Speed after catching the ball is equal to 0.074 m/s
Answer: The temperature after another 5 minutes is 68.5°c

Answer:
Vrel_jon's = 15 [m/s] to the right
Explanation:
Relative velocity is defined as the relative motion between two bodies, taking into account the directions of motion.
Relative velocity is defined as the relative motion between two bodies, taking into account the directions of motion. The relative velocity is defined as the algebraic sum of the velocities, if the movements are opposite the vectors are subtracted, as will be done below.
Vrel = 20 - 5 = 15 [m/s]
A person watching Jon sees him moving to the right at a speed of 15 [m/s]
