WebSep 30, 2015 · A ball of mass 0.2 kg is dropped from a height of 2.5 m above horizontal ground. After hitting the ground it rises to a height of 1.8 m above the ground. Find the magnitude of the impulse received by the ball from the ground The answer in the book I'm using says $2.59$ Ns. WebIf you want to find the time that it takes to hit the ground, set h=0 and use the quadratic formula to solve for t. 0=-16t^2+64t+5 The quadratic formula should give you two answers: t=-0.77 and t=4.077 You have to choose the positive answer, as time cannot be negative. Therefore, the ball hits the ground at 4.077 seconds.
WebHere we talk about how to use the quadratic formula to determine the time it will take for the ball to hit the ground. WebFeb 25, 2024 · When the point the object hits the ground, h(t) become 0, Then, For the quadratic equation solution is determined by the formula. Where, a = -16, b = 27, c = 10. Substitute all the values in the formula; Time can not be negative. so, x = -0.3125 rejected. Hence, It will take 2 seconds for the object to hit the ground. To know more about ...

WebThe range of the projectile depends on the object’s initial velocity. If v is the initial velocity, g = acceleration due to gravity and H = maximum height in metres, θ = angle of the initial velocity from the horizontal plane (radians or degrees). The maximum height of the projectile is given by the formula: H = v 0 2 s i n 2 θ 2 g.
WebWhat would be the value of s(t) when the ball hit the ground? Value of s(t): feet. Using the formula given for s(t), you can find the time at which the ball would hit the ground by setting s(t) equal to zero and solving for t. If you do this, you get a quadratic equation for t. Find this equation and complete the following entries: -16 +2 + t+ = 0.
