The period is how long it takes for something to repeat. 40 vibrations repeat in 20 seconds so 1 vibration will take 0.5 seconds to repeat.

Find the range of projectile launched at the angle of 45 with an intial velocity of 25 m/s
Mekhanik [1.2K]

Answer:

10

Explanation:

Given that :

Initial Velocity (u) = 25 m/s

Range can be obtained using the relation :

Range = (u² * sin2θ) / g

g = 10m/s ; θ = 45

Range = [10² * sin2(45)] / 10

Range = [100 * 1] ÷ 10

Range = 10
