Answer: He has only move 0.2 yards
Explanation: When you subtract 18.3 from 18.5 you get 0.2 and that is how much he's moved
Answer:
1.29 s
Explanation:
Given:
Δy = 1.40 m
v₀ = 0 m/s
a = 1.67 m/s²
Find: t
Δy = v₀ t + ½ at²
(1.40 m) = (0 m/s) t + ½ (1.67 m/s²) t²
t = 1.29 s
Answer:
Ice cube, molecules, melting, zero degrees, liquid, faster, temperature, 100 degrees, steam
The thermal energy was produced is 116J
<h3>What is the thermal energy produced?</h3>
Now we know that the frictional force produces the energy that is lost as heat as the body slides down the incline. The magnitude of the frictional force is obtained from;
Ff= μmgcosθ
Ff = 0.65 * 5.0 kg * 9.8 m/s^2 * cos 25
Ff = 29 N
Hence, the thermal energy is;
29 N * 4.0 m = 116J

Explanation:
we use the formula for that 6s duration ....
<h2> S = ut + 1/2 at² </h2><h3>s = displacement </h3><h3>u = initial velocity </h3><h3>a = acceleration </h3><h3>t = time </h3>
so , S = (5 × 6) + (1/2 × 2 × 6 × 6 )
S = 30 + 36
<h3> S = 66m</h3>
and we can use this formula to find the final velocity.......
<h2> V = U + at </h2><h3>V = final velocity </h3><h3>a = acceleration </h3><h3>u = initial velocity </h3><h3>t = time </h3>
so , V = 5 + (2×6)
V = 5 + 12
<h3> V = 17m/s </h3>
