What is the initial velocity of a ball thrown upward?

A ball is thrown upward with an initial velocity of 20 m/s. How long will the ball take to reach its maximum height? At the maximum height the ball will have an instantaneous velocity of zero. The formula for instantaneous velocity is

How fast does the ball reach its maximum height after 2s?

That means velocity will decrease by 10 m/s every second. Hence, if the ball was thrown with 20 m/s, after 1 s its velocity would be reduced to 10 m/s and after 2 s it would come to rest. Hence, it will reach its maximum height after 2 s.

What is the average deceleration of the ball at the highest point?

So to go from 20 m/s to zero, will take two lots of zero to 10 in reverse, thats 2 seconds, average speed of 5 m/s and 15 m/s, for each second respectively, thats a total average of 20 metres per second deceleration over two seconds for a total average speed of 20 m/s Speed of the ball at the highest point is zero m/s.

What is the maximum height of a moving object with average velocity?

And since, change in velocity is constant every second, we can take average velocity to be the mean of initial and final velocities, which would be (20 + 0)/2 = 10m/s and it travels for 2s giving it a displacement of 2*10 = 20 m which would be its maximum height. Its speed will reduce by 10m/s per second, so it will rise for 2 sec before it stops.

What is the velocity of the projectile after 2 seconds?

The high point of the trajectory. The only velocity will be the original 25m/s horizontally. The average vertical velocity is 10m/s so at 2 seconds it has reached 20m high. The horizontal velocity is 25 m/s so after 2 seconds → 50 metres. It is at x = 50, y = 20 and travelling horizontally at 25 m/s.

What type of energy does a ball have when it throws?

When the ball is thrown it only has Kinetic energy, but when it is at a particular height it has both kinetic and potencial energy. The total energy is always the same for a object. TE=KE+PE KE: Kinetic Energy is possessed by object due to its motion (0.5*m*v*v).

What happens when you throw a ball vertically upward?

Motion of a ball thrown vertically upwards. You must have seen someone throwing a ball vertically upwards or probably you have thrown it yourself. Yes, the ball thrown vertically upwards goes up for a while and then stops and starts to come down and touches the ground with a bang if you can’t catch it.
