Question

A projectile is thrown with a velocity of 10 ms⁻¹ at an angle of 30° with horizontal. The value of maximum height gained by it is *

(a) 1 m

(b) 1.25 m

(c) 2 m

(d) 2.5 m​

Answer 1

Answer:. b) 1.25 m

Formula used :

Max. height , H = u²sin²θ/2g

Putting values in the above formula,

H = (10)² (1/2)²/ 2×10

= 5/4

= 1.25 m
