Problem 6.38 A projectile is fired at an upward angle of 40.0 degree from the top of a 245-m cliff with a speed of 235m/s. Part A What will be its speed when it strikes the ground below? (Use conservation of energy.) V =m/s
A 40.0-kg projectile is fired at an angle of 30.0° above the horizontal with an initial speed of 142 m/s from the top of a cliff 118 m above level ground, where the ground is taken to be y = 0. (a) What is the initial total mechanical energy of the projectile? (Give your answer to at least three significant figures.) (b) Suppose the projectile is traveling 100.6 m/s at its maximum height of y = 328 m. How much...
A 60.0-kg projectile is fired at an angle of 30.0° above the horizontal with an initial speed of 124 m/s from the top of a cliff 144 m above level ground, where the ground is taken to be y = 0. (a) What is the initial total mechanical energy of the projectile? (Give your answer to at least three significant figures.) (b) Suppose the projectile is traveling 87.9 m/s at its maximum height of y = 304 m. How much...
A 44.0-kg projectile is fired at an angle of 30.0° above the horizontal with an initial speed of 128 m/s from the top of a cliff 160 m above level ground, where the ground is taken to be y = 0. (a) What is the initial total mechanical energy of the projectile? (Give your answer to at least three significant figures.) ____J (b) Suppose the projectile is traveling 90.7 m/s at its maximum height of y = 331 m. How...
1) A projectile is fired horizontally from the top of a cliff as shown: 1.00 km The projectile hits the ground 4.00 s later at a distance of 1.00 km from the base of the cliff. a 5 pts) What is the height of the cliff? b - 5 pts) What was the initial speed of the projectile? c - 5 pts) What is the speed of the projectile just before it hits the ground?
A projectile is fired into the air from the top of a 200-m cliff above a valley. Its initial velocity is 60 m/s at 60° above the horizontal. (a) Where does the projectile land? (b) How long does the ball in air? (c) At what times velocity is 40m/s? I.
a projectile is fired into the air from the top of a cliff 100m above a valey floor. its initial veloity is 80 m/ at an angle of 25 above the horozontal. assuming free fall conditions dtermine -the displacment of the projectile after 1 second with respect to the base of the cliff -total time of flight -the horozontal distance from the base of the cliff With the steps please
A projectile is fired at an upward angle of 38.0 degrees from the top of a 135m high cluff with a speed of 165 m/s. What will be its speed when it strikes the ground below? (Use conservation of energy) I would really appreciate a thorough walkthrough of this problem, thank you!
a projectile is launched from ground level to the top of a cliff which is 95 m away and 155 m high. If the projectile lands on top of the cliff 7.6 s after it is fired, what was its initial velocity? (Be careful what you assume).
Question 4 10 pts A projectile is fired from the edge of a 150-m cliff with an initial velocity of 180 m/s at an angle of 30° with respect to the horizontal. Neglecting air resistance, find the time it takes for the projectile to strike the ground in seconds) 180 m/s 130 150 m
