C) both moving and non-moving objects
As, it is same as the Newton's first law motion
Answer:
20.1 m
Explanation:
First, find the time it takes for the cannonball to travel the horizontal distance of 50.0 m.
Given (in the x direction):
Δx = 50.0 m
v₀ = 68 cos 25° m/s
a = 0 m/s²
Find: t
Δx = v₀ t + ½ at²
(50.0 m) = (68 cos 25° m/s) t + ½ (0 m/s²) t²
t = 0.811 s
Now find the vertical displacement after that time.
Given (in the y direction):
v₀ = 68 sin 25° m/s
a = -9.8 m/s²
t = 0.811 s
Find: Δy
Δy = v₀ t + ½ at²
Δy = (68 sin 25°) (0.811 s) + ½ (-9.8 m/s²) (0.811 s)²
Δy = 20.1 m
Answer:
9.5 seconds
Explanation:
You need to make the ending speed into meters per sec.
So it would be 120km/h = 33.33m/s
If the acceleration rate is 3.5m/s, then the final answer would equal to 9.5 seconds
Also btw rounding it up is a good idea too so 10 seconds if you round
Answer:mechanical advantage of a wheel and axle is the ratio of the radius of the wheel to the radius of the axle in the absence of friction
Explanation:
The mechanical advantage of a wheel and axle is equal to the ratio of the radius of the wheel to the radius of the axle in the absence of friction
