Here we will solve selected **Projectile Motion Numericals for class 11** and will also provide solution guidance. To get a good grasp on this chapter we need to solve some numerical problems, which really helps us a lot to understand the basics and use the formulas.

Earlier we published posts on the derivation of the projectile motion equations and also published an online calculator for projectile motion formula sets. Here we go with our post on numerical problems. (with a few harder problems). This numerical set is apt for the **class 11** physics syllabus also. (& for grade 12 HSC as well)

## Projectile Motion Numericals for class 11 with solution

Q1 ) A particle is projected from the surface of the earth with a speed of 20 m/s at an angle of **30 degrees with the horizontal. Determine the (a) time of flight (b) range (c) maximum height, and (d) equation of trajectory for this projectile motion (take g = 10 m/s^2)**

Q2 ) A particle is projected from the surface of the earth with a velocity of 20 m/s at an angle of 30 degrees to the horizontal as shown in the figure. A wall of height 3 m is there at a horizontal distance of 10 m from the point of projection. Find out whether the particle hits the wall or not. g = 10m/s^2

**Solution: **Here we have to find out the value of vertical displacement y when horizontal displacement is x = 10 m. If the value of y comes out to be less than the height of the wall then the projectile hits the wall otherwise not.

[ Tips: This can be checked **by using the trajectory equation** (section A below) or **by using the equations of horizontal and vertical displacements** (section B below). Note: You may use either A or B while attempting the numerical in exams.]

**So, it is evident that the particle will not hit the wall.**

Q3 ) A particle is projected from the ground with a velocity of 20 m/s at an angle of 30 degrees with the horizontal. Determine the time at which the vertical displacement of the projectile is 3 m. (g = 10 m/s^2)
