The fully loaded bus accelerates uniformly from rest to a speed of 14 m / s. The time taken to reach a speed of 14 m / s is 20 s
.
1 answer:
Answer:
0.7m/s^2
Explanation:
acceleration=(final-initial velocity)/time
x=(14-0)/20
x=14/20
x=0.7

<em>✔ We have : a = v/Δt </em>
The car's acceleration is therefore 6 m/s².
Answer:
constant velocity unless acted on my an opposite force
Answer:
No
Explanation:
Some objects gain momentum.
Explanation:
Given:
v₀ = 250 mph
v = 0 mph
t = 25 s
Find: a
v = at + v₀
(0 mph) = a (25 s) + (250 mph)
a = -10 mph/s
