One explanation for how the receiver of a passed football knows to speed up or slow down to catch the ball is that he keeps the tangent of the angle of the ball’s velocity vector constant. Explain.

layer a is the exosphere and layer b is the thermosphere.   is the answer i think but i hope this .

this a false

explanation:

can be answered using momentum.

momentum = p

p1= mass1 * velocity1

p1 = p2

therefore

p1 = 6kg * 4m/s

p1 = 24kgm/s

p2=m2 * v2

24 kgm/s = 7kg * v2

v2 = 24 kgm/s / 7kg

v2= 3.42 m/s
