Adaredevil is shot out of a cannon at 45.0° to the horizontal with an initial speed of 31.0 m/s. a net is positioned a horizontal distance of 48.5 m from the cannon. at what height above the cannon should the net be placed in order to catch the daredevil?

s = vcos(x)t

50 = 25cos(45)t

cos(45)t = 2

t = 2/cos(45) = 2sqrt(2)

h = vsin(x)t + gt^2/2

h = 25sin(45)*2sqrt(2) - 4.9*8

h = 10.8 metres

Explanation:

24.5 m

Explanation:

First, find the time it takes for the daredevil to travel 48.5 m horizontally:

x = x₀ + v₀ t + ½ at²

(48.5 m) = (0 m) + (31.0 m/s cos 45.0°) t + ½ (0 m/s²) t²

t = 2.21 s

Next, find the vertical position reached at this time:

y = y₀ + v₀ t + ½ at²

y = (0 m) + (31.0 m/s sin 45.0°) (2.21 s) + ½ (-9.8 m/s²) (2.21 s)²

y = 24.5 m

The net should be placed 24.5 meters above the cannon.

think its the third option

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
