Solution Summary

The following posting helps with problems involving acceleration due to gravity, time and horizontal velocity.

Solution Preview

All of these questions have to do with acceleration due to gravity, time and horizontal velocity. First, let's consider some basic logic. We know that an object that falls from rest, like in question 1, will accelerate towards the ground at the rate defined by the acceleration due to gravity. It takes time to accelerate the object and for it to reach the ground. During this time, if the object started off perfectly still, it would simply travel that vertical distance.

Let's consider the first question.
We can figure out this time using kinematic equations. Firstly, let's consider what we know:
v0 ...

  • Physics Problems: Velocity, Impact, Speed

    The balloon hits the ground 1.8 seconds after it is dropped and has a velocity V1 on impact. (Neglect Teflonian air resistance.) What is the acceleration due to gravity on the planet Teflon?

  • Velocity and acceleration

    The force on a falling body is only the force due to gravity called weight of the body. This force produces acceleration in the body which is called acceleration due to gravity.

  • Workout velocity and range of shell fired

    Answer: The horizontal and vertical motion of a projectile are considered undependably of each other because there is no horizontal acceleration on the projectile while the vertical acceleration is equal to g (acceleration due to gravity).

  • Projectile Motion: Horizontal range and time of flight.

    When a projectile fired at angle  to the horizontal with velocity u, as the acceleration due to gravity g is vertically downwards, the velocity of the projectile can be resolved in horizontal and vertical components.

  • Motion in Plane: Rocket lanching and then projectile motion

    Let the time from this point to the ground is t seconds. During this time the vertical displacement is - y1 and the acceleration is that due to gravity g = - 9.8 m/s2.

  • Motion in two dimensions: Projectile motion.

    Here we can solve the motion separately in horizontal and vertical directions. When the ball falls the only force acting on it is its weight vertically down and due to that the acceleration is the acceleration due to gravity 9.8 m/s2.

  • Kinematics

    direction) a= acceleration due to gravity = -9.81 m/s^2 ( negeative because it is downwards) Thus 0= 1- 1/2 (9.81) t^2 Solving for t t= 0.4515 s In the horizontal direction acceleration = 0 Therefore distance

  • Mechanics: Motion on Incline, Banking on Tracks, Projectile.

    The force acting on a projectile is the gravitational force and hence the acceleration is that of acceleration due to gravity which is vertically downwards.

  • Motion in two dimensions, projectile motion.

    As there is no force in horizontal direction the horizontal velocity remains constant while the velocity in vertical direction increases from zero due to the force of gravity.
