no the answers r b, d, r, and f
Explanation:
Answer:
36 minutes
Explanation:
Distance= Time*Speed
Let time taken to go to city be x hours, therefore, time to travel back is (2-x) hours
The distance to and from the city are equal hence
15x=35(2-x)
15x=70-35x
50x=70 hence x=70/50=1.4 hours
Time to drive home will be 2-x=2-1.4=0.6 hours
0.6*60=36 minutes
Therefore, time to travel back home is 36 minutes
speed Δv = v₂ = 8.15ms⁻¹
v₁ = 0ms⁻¹
time =t = 5s
acceleration = a = speed / time taken
a = Δv / Δt ( as Δv = v₂ - v₁)
a = 8.15ms⁻¹ / 5 s
a = 1.6ms⁻²
Answer:
0.631 m
6.53315 J
Explanation:
m = Mass = 2.47 kg
v = Velocity = 2.30 m/s
k = Spring constant = 32.8 N/m
A = Amplitude
In this system the energy is conserved
The amplitude is 0.631 m
Mechanical energy is given by
The mechanical energy is 6.53315 J
