A ball of mass 0.6kg is projected vertically upwards with speed 22.4 m s- from a point which is 1.5 m above horizontal ground. The ball moves freely under gravity until it reaches the ground. The ground is soft and the ball sinks 2.5 cm into the ground before coming to rest. The ball...
<p>To find the time taken by a particle projected vertically upwards to reach its highest point, we can use the following steps:</p><p>1. <strong>Identify the Initial Velocity (u)</strong>: The particle is projected with an initial velocity of \( u =
A ball is thrown vertically upwards. Ignoring air resistance, which of the following statements is true about the ball's motion? A. The ball has a constant acceleration throughout its motion B. The velocity of the ball is zero at the highest point, so the acceleration is also zero C. ...
The ball is projected vertically down with a velocity of 10sqrt(3)m/s from a height of 20m .On the hitting the ground if it loses 40% of its energy the height to which it bounces is (g=10ms^(-2)) View Solution A helicopter is rising vertically up with a velocity of5ms–1. A...
