Jamieson is competing in his school’s 3.0-metre diving competition. For his last dive, he is performing a forward somersault. The duration of the dive must be exactly 1.75 seconds or he will under- or over-rotate before hitting the water. He jumps upwards off the board with a vertical velocity of 6.0 m s−1 and takes $t$t​ seconds to land in the pool. Take the upwards direction as positive.Which of the following correctly describes the initial velocity during the jump?A0 m s−1B6.0 m s−1C−6.0 m s−1D6.0 m s−2

If an object is thrown downward, the initial velocity is.

An object is thrown vertically upwards with an initial velocity of m/s. (take g=10m/s2 Find –(innotebook)-(i) time taken to reach maximum height(ii) maximum height reached(iii) velocity after 5 seconds

If a ball is dropped from a 100 m cliff, it accelerates at a constant rate of 9.8 m/s2. Assuming its initial velocity is 0 m/s, its initial position is 0 m and its final position is 100 m away from the initial position, what is the velocity of the ball when it hits the ground?
