Question

3. Select ONE correct answer
A projectile is thrown with a velocity of 18 m/s at an angle of 60° with horizontal. The interval between the
moments when speed of the projectile is 15 m/s is: (g = 10 m/s2)​

Answer 1

Answer:

12/5 is the answer

Explanation:

v cos 60°= vcos thetha

18 × 1/2. = 15× cos thetha

cos thetha = 3/5

t= 24 / 10 = 4/5

sin thetha = 12 / 5 ( multipling both)
