Question

four balls P, Q, R and S are thrown with equal velocities at angles of 10° , 30° , 45° and 60° respectively. Which ball will fall at the maximum distance?
a) P
b) Q
c) R
d) S​

Answer 1

Answer P

Explanation:

Because 10 degree is more bended so the answer is P in my opinion

Answer 2

Given:

P, Q, R, and S are the 4 balls and thrown with equal velocities at angles of 10°, 30°, 45°, and 60° respectively.

To Find:

Which ball will fall at the maximum distance?

Solution:

The maximum distance covered is also known as a range(R).

R = u²sin2θ/g ---------- (1)

The above equation is maximum when sin2θ = 1

2θ = sin⁻¹(1)

2θ = 90°

θ = 45°

Hence, The maximum distance is covered by R at an angle of 45°.
