Use the projectile motion equations
H = v^2 x sin^2(θ) ÷ 2g
t = 2 x v x sinθ ÷ g
R = v^2 x sin2θ ÷ g

Answer:
D is the correct answer
Explanation:
A) shows low accuracy and high precision since they missed the bull's-eye but are all grouped together.
B) Shows high accuracy and high precision
C) Shows high precision
D is the only one that shows both low accuracy and low precision
Answer:
(A) Original speed= 9.22 m/s
(B) Acceleration= -1.0099 m\s^2
Explanation:
A truck covers 40m in 7.10 secs
The truck slows down at a uniform velocity of 2.05 m/s
(A) The original speed can be calculated as follows
Vo= 2(40)/7.10 - 2.05
= 80/7.10 - 2.05
= 11.2676 - 2.05
= 9.22m/s
(B) The acceleration can be calculated as follows
a= Vf-Vo/t
= 2.05-9.22/7.10
= -7.17/7.10
= -1.0099m/s^2
