What is the initial velocity of a ball thrown upwards?

Two balls of equal masses are thrown upwards, along the same vertical direction at an interval of 2 seconds, with the same initial velocity of 40 m/s . Then these collide at a height of (Take g = 10 m/s^2 ).

Do two balls with the same velocity travel in the same direction?

Velocity is a vector – if two balls are thrown with the ‘same velocity’ they will travel in the same direction, not in opposite directions. And the answer to you question is no.

How long does it take to reach the ground when thrown upwards?

The ball thrown upwards with speed u from top of tower when comes down back to same height (top of tower), will have same speed with which it was thrown upwards i.e. u. Further it will take 2 sec to reach ground. This is because the second ball thrown downwards with speed u, did take 2 sec.

What does the delay depend on when a ball is thrown?

The delay will depend on the speeds at which the balls are thrown – upwards and downwards, respectively.

“a ball is thrown upwards with initial velocity 20 m/s. After reaching maximum height, on “a ball is thrown upwards with initial velocity 20 m/s. After reaching maximum height, on the way down it strikes a bird which is 10 m above the ground.

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 to which the ball will rise?

(1) The maximum height to which the ball rises = 122.5 m (2) The total time ball takes to return to the surface of the earth = 5 + 5 = 10 sec. Was this answer helpful?

Why is the velocity of a falling ball not symmetric?

It’s interesting to note that the velocity is no longer symmetric across v=0 – this is because air resistance adds to the gravitational force when the ball is rising, but subtracts from it while the ball is falling. A soft ball is thrown vertically upward with the velocity of 3.5 m/s.
