What is the velocity after 4 seconds?

The competition just started. What will be your velocity after 4 seconds? Set initial velocity to zero, you’re not moving at the beginning of the race. Multiply the acceleration by time to obtain the velocity change: velocity change = 6.95 * 4 = 27.8 m/s .

What is the height reached of the stone?

When the stone reaches its maximum height, for a moment the velocity of the stone becomes zero at that instant and then it starts falling back towards ground. So, the maximum height to which the stone can reach is 80 m.

What maximum height a stone will reach if it is thrown upwards with a velocity of 20m sec?( G 10m sec 2?

∴ The Maximum height reached by the stone when it is thrown vertically thrown with a velocity of 20 m/s and g as 10 m/s² is 5m.

What is the velocity of the stone just before it hits the ground?

19.0 metres per second
Thus, the velocity of stone just before hitting the ground will be 19.0 metres per second, Q.

What maximum height a stone will reach if it is thrown upward with a velocity of 20 ms?

→ S = 20m. Hence, The maximum Height reached by stone is 20m and in 2s.

What is the velocity of a stone thrown vertically up from bridge?

A stone is thrown vertically up from a bridge with velocity 3 ms^-1 if it strikes the water under the bridge after 2 s, the bridge is at a height of ( g = 10m/s^2)

What is the initial speed of the second stone?

Both strike the water simultaneously, then the initial speed of the second stone is > A stone is dropped into wat… A stone is dropped into water from a bridge 44.1 m above the water. Another stone is thrown vertically downward one second later. Both strike the water simultaneously, then the initial speed of the second stone is = 3sec.

What is the initial velocity of the Earth due to gravity?

Final velocity is 60 meters per second. Time is 4 sec. Earths gravitation acceleration is 9.8 meters per second squared. Solving, we find due to gravity alone it would be traveling at 39.2 meters per sec. Difference between 60 m/s and 39.2 m/s is 20.8 m/s of initial velocity.
