Projectile Motion Word Problems Worksheet With Answers Pdf
A projectile is an object that is thrown or launched into the air and then moves in a curved path under the influence of gravity. Projectile motion is a form of motion in which an object or particle is thrown near the earth's surface, and it moves along a curved path due to the force of gravity.
If you are a student of physics or engineering, it is essential to solve projectile motion word problems. These problems help you to apply the concepts you have learned in class and improve your problem-solving skills. In this article, we will provide you with a Projectile Motion Word Problems Worksheet with Answers Pdf to help you practice and improve your knowledge.
What is Projectile Motion?
Projectile motion is the motion of an object that has been thrown or launched into the air, and it moves due to the force of gravity. When an object is thrown or launched, it moves along a curved path until it hits the ground or other object. The path that the object follows is called the trajectory.
The trajectory of a projectile is affected by several factors, including the initial velocity, the angle at which it is thrown, and the force of gravity. The initial velocity is the speed at which the object is thrown, and the angle at which it is thrown determines the direction and shape of the trajectory.
The force of gravity acts on the object as it moves, causing it to accelerate downward at a rate of 9.8 meters per second squared (m/s2). This acceleration is called the acceleration due to gravity and is denoted by the symbol g.
The formula for calculating the height of a projectile at any time t is given by:
Where h (t) is the height of the projectile at time t, h0 is the initial height, v0 is the initial velocity, g is the acceleration due to gravity, and θ is the angle at which the projectile was thrown.

Now let's take a look at some projectile motion word problems to help you practice and improve your skills. We have provided a Projectile Motion Word Problems Worksheet with Answers Pdf for you to download and use.
Problem 1:
A ball is thrown from the top of a 50-meter tall building with an initial velocity of 20 m/s at an angle of 45 degrees to the horizontal. Calculate the time it takes for the ball to hit the ground, the horizontal distance traveled by the ball, and the maximum height reached by the ball.
Solution:
Step 1: Calculate the time it takes for the ball to hit the ground
Using the formula t = 2v0 sin θ / g, we get:
Substituting the values, we get:
Therefore, the time taken for the ball to hit the ground is approximately 2.04 seconds.
Step 2: Calculate the horizontal distance traveled by the ball
Using the formula d = v0 cos θ x t, we get:
Substituting the values, we get:
Therefore, the horizontal distance traveled by the ball is approximately 40.8 meters.
Step 3: Calculate the maximum height reached by the ball
Using the formula h = (v0 sin θ)2 / 2g, we get:
Substituting the values, we get:
Therefore, the maximum height reached by the ball is approximately 25.1 meters.
Problem 2:
A cannonball is fired horizontally with an initial velocity of 80 m/s from the top of a cliff that is 100 meters high. Calculate the time it takes for the cannonball to hit the ground and the horizontal distance traveled by the cannonball.
Solution:
Step 1: Calculate the time it takes for the cannonball to hit the ground
Using the formula t = √2h / g, we get:
Substituting the values, we get:
Therefore, the time taken for the cannonball to hit the ground is approximately 4.52 seconds.
Step 2: Calculate the horizontal distance traveled by the cannonball
Using the formula d = v0 x t, we get:
Substituting the values, we get:
Therefore, the horizontal distance traveled by the cannonball is approximately 362 meters.
