What is the horizontal velocity of the ball at time 2 seconds?
The vertical velocity of a projectile changes by 9.8 m/s each second, The horizontal motion of a projectile is independent of its vertical motion….
| Time | Horizontal Velocity | Vertical Velocity |
|---|---|---|
| 0 s | 73.1 m/s, right | 19.6 m/s, up |
| 1 s | 73.1 m/s, right | 9.8 m/s, up |
| 2 s | 73.1 m/s, right | 0 m/s |
| 3 s | 73.1 m/s, right | 9.8 m/s, down |
How do you find the magnitude of velocity?
To calculate the magnitude of the velocity at any point in time, multiply the constant acceleration rate times the time difference and then add it to the initial velocity. As an example, if you dropped a rock off a cliff, its velocity increases by 32 feet per second, every second.
What is the magnitude of the acceleration of the ball just before it strikes the ground?
The acceleration of the ball just before it strikes the ground is g=9.8 m/s2 g = 9.8 m / s 2 i.e. the gravitational acceleration.
What is the magnitude of the final velocity?
Final velocity (v) of an object equals initial velocity (u) of that object plus acceleration (a) of the object times the elapsed time (t) from u to v. Use standard gravity, a = 9.80665 m/s2, for equations involving the Earth’s gravitational force as the acceleration rate of an object.
How do you calculate the velocity of a vertically thrown ball?
If a ball is thrown vertically upwards with an initial velocity V0then here is a set of formula for your quick reference. 1) Maximum height reached = H = V02/ (2 g) 2) Velocity at the highest point = 0 3) Time for upward movement = V0/g 4) Time for downward movement = V0/g 5) Total time of travel in air = (2 V0)/g
What is the final velocity of the ball when it stops?
After a certain time period t, the ball reaches a height beyond which it can’t move upwards anymore and stops there i.e. its velocity becomes zero at that height. And for this upward movement, the final velocity v2 is 0 because the ball has stopped at the end of this upward traversal.
What happens to the vertical velocity as an object rises?
(c) The velocity in the vertical direction begins to decrease as the object rises; at its highest point, the vertical velocity is zero. As the object falls towards the Earth again, the vertical velocity increases again in magnitude but points in the opposite direction to the initial vertical velocity.
What happens horizontally and vertically when an object goes off a cliff?
Looking at this problem as what is happening horizontally and vertically, you should get the idea that this is just like the components that we were just working on a couple of lessons back. The horizontal and vertical components of the motion of an object going off a cliff are separate from each other, and can not affect each other.
