A stone is thrown with an angle of 530 to the horizontal with an initial velocity of 20 m/s, assume g=10 m/s2. Calculate: a) The time it will stay in the air? b) How far will the stone travel before it hits the ground (the range)? c) What will be the maximum height the stone will reach?
10 m/s
if the bal is thrown by making 45 degree angles. with the ground..it will travel maximum distance...
It is important when a heavy load is above the ground level, let's say the fridge on the truck which can not just be thrown to the ground so you need an incline plane for safety
The ball was thrown horizontally at 10 meters per sec, and the thrower's arm was 78.4 meters above the base of the cliff.
As the rock rises, its horizontal component of velocity remains constant. This is because there is no horizontal force acting on the rock to change its velocity in that direction. The only force affecting the rock's motion is gravity, which acts vertically, causing its vertical component of velocity to decrease until the rock reaches its peak height and then falls back down.
No, a ball thrown at an angle of around 45 degrees will typically go the furthest. This launch angle combines vertical and horizontal components of velocity to achieve the maximum range. A ball thrown almost horizontally will have a lower trajectory and be affected more by air resistance, causing it to have a shorter range.
The thrown ball will have a greater speed when it reaches ground level because it has a horizontal component of velocity in addition to the vertical component. The rock only has a vertical component of velocity due to gravity.
A motion thrown at an angle is called projectile motion. It involves an object being launched at an angle relative to the ground and following a curved path due to the combination of its horizontal and vertical velocities.
The rock will have a greater speed when it reaches the ground level compared to the ball thrown horizontally because the rock will be accelerated by gravity as it falls vertically, while the ball thrown horizontally will only have its initial horizontal velocity.
If thrown horizontal from same height the faster object will travel farther horizontally, but time to fall is the same. If thrown straight up, the faster object will take longer to fall
When a body is thrown horizontally with uniform speed, there is no change in the horizontal velocity, so the horizontal component of acceleration is zero. The only acceleration acting on the body is due to gravity in the vertical direction.
The horizontal speed of the projectile remains constant as there is no force acting in the horizontal direction to change it. Therefore, the horizontal speed of the projectile after 3 seconds will remain at 4 m/s.
The speed of a ball thrown upward upon striking the ground will be the same as the speed at which it was thrown, but in the opposite direction. The speed of a ball thrown downward upon striking the ground will be faster than the speed at which it was thrown due to the acceleration from gravity.
a stone is thrown from the top of a building with an initial horizontal velocity of 20 m/s if it is thrown from a height of 30 m and air resistance is neglected, find: a) time it takes the stone to reach the ground b) range
The object will follow a parabolic path due to gravity and its horizontal speed of 45 m/s will remain constant. The time it takes to reach the ground can be calculated using kinematic equations. Its final velocity will be the vector sum of its horizontal and vertical components.
No, objects fall at the same rate regardless of their horizontal velocity. Both objects would hit the ground at the same time if dropped from the same height.
