Answer:
the force acting on the team mate is 1.19 kN.
Explanation:
given,
mass = 196 lbm
while tackling, the deceleration is from velocity 6.7 m/s to 0 m/s
time taken for deceleration = 0.5 sec
F = mass × acceleration
acceleration = 
= -13.4 m/s²
1 lbs = 0.453 kg
196 lbs = 196 × 0.453 = 88.79 kg
F = 88.79 × 13.4
F = 1189.786 N = 1.19 kN
hence, the force acting on the team mate is 1.19 kN.
Answer:
B.C. D. G.
Explanation:
A vector quantity, has both magnitude and direction. A tip to remember is if you can add a direction to it! You wouldnt say 30 pounds north, but you would say 30 mph north.

Answer:
Total speed of the insect as seen by a person standing on the side of the road is 22 m/s
Explanation:
There i a composition of velocities, since the air inside the bus is moving at the same speed as the bus, and the insect flying relative to it.
So for an observer on the side of the road, the insect is flying at a speed of :
20 m/s + 2 m/s = 22 m/s
