Answer:
B
Explanation:
of 39.2 m/s?
Answer:
304.89m
Explanation:
Given
acceleration a = 2.52m/s²
final speed v = 39.2m/s
initial speed = 0m/s (car accelerates from rest)
Using the equation of motion below to get the distance of Doc brown from Marty;
v² = u²+2as
substitute the given parameters
39.2² = 0²+2(2.52)s
1536.64 = 0+5.04s
divide both sides by 5.04
1536.64/5.04 = 5.04s/5.04
rearrange the equation
5.04s/5.04 = 1536.64/5.04
s = 304.89m
Hence He and Marty must stand at 304.89m to allow the car to accelerate from rest to a speed of 39.2 m/s?
Answer;
Proof Surrogate.
Explanation;
A claim masquerading as proof or evidence, when no such proof or evidence is actually being offered.
Proof Surrogate is an expression used to suggest that there is evidence for a claim without actually citing any evidence. For example;
-“Scientists have known that aliens exist for years now.”
-“Everyone knows that bottled water is better for you than tap water.”
Answer:
128 m
Explanation:
displacement = velocity x time
32 x 4 = 128
Answer:
Displacement= velocity X time
= 32 X 4
=128m/s
