Air resistance is negligible. What is the speed of the object after 5.0 s? 21 m s–1 36 m s–1 28 m s–1 50 m s–1 2 / 5 2) A motorcycle stunt-rider moving horizontally takes off from a point 1.25 m above the ground, landing 10 m away as shown. What was the speed at take-off? 5.0 m s–1 10 m s–1 20 m s–1 15 m s–1 3 / 5 3) A ball is thrown horizontally at a speed of 25 m/s from the top of a cliff. If the ball hits the ground 4.0 s later, how high is the cliff? 40 m 6.3 m 80 m 100 m 4 / 5 4) The figure below shows the path of a ball leaving the ground at point X and about to hit the ground at point Z. If air resistance is negligible, the vertical component of velocity is maximum at Y. acceleration is the same at Y as at Z. velocity is the same at X and Z. displacement is minimum at Y. 5 / 5 5) A projectile is launched at point O and follows the path OPQRS, as shown. Air resistance may be neglected. Which statement is true for the projectile when it is at the highest point Q of its path? The horizontal component of the projectile's acceleration is zero. The kinetic energy of the projectile is zero. The horizontal component of the projectile's velocity is zero. The momentum of the projectile is zero. Your score is Restart quiz
