A particle is projected vertically upwards at 7 m/s from a point 38.7 m above the ground. Find the maximum height the particle can reach. Consider the acceleration due to gravity to be 9.8 m/s2.
A ball is projected vertically upwards from the edge of a cliff, which is 186.2 m above the ground. If during the third second it covers a distance of 2.45 m upwards, find the time that the ball takes to reach the ground at the bottom of the cliff. Take the gravitational acceleration to be 9.8 m/s2.
A body was projected vertically downwards from the top of a tower whose height is 80 m. Given that it covered 35.9 m during the 1st second of its motion, find the time taken to reach the ground rounded to the nearest two decimal places. Let the acceleration due to gravity .
A body fell vertically from the top of a tower. It covered 86.73 m in the final second before hitting the ground. Determine the height of the tower rounding your answer to the nearest two decimal places. Let the acceleration due to gravity .
A body was projected vertically downwards at 66.9 m/s from the top of a tower that is 457 metres high. Determine the distance that the body covered in the last second before it struck the ground. Take the acceleration due to gravity .
