Need it fast if possible thank you A girl throws a rock horizontally with a speed of 12 m/s from a bridge. It falls 2.28 s before hitting the water below Neglect air resistance. How high is the bridge from the water below? How far horizontally does the rock travel before striking the water?
A girl throws a rock horizontally with a speed of 12 m/s from a bridge. It falls 2.28 s before hitting the water below. Neglect air resistance. (a) How high is the bridge from the water below? (b) How far horizontally does the rock travel before striking the water?
Please solve for me 12, 13, 14 problems for me. Thank you 12) What initial velocity is needed to fire an arrow 450 m? Assume the optimum angle from part c) above. 13) A cliff-jumper runs off a 28 m cliff. The rocks below jut out 5.2 m from the base of the cliff. What is the minimum horizontal velocity needed to hit the water and avoid the rocks? 14) A large rock falls from the side of a cliff....
Please show me the work thank you 10) A projectile is launched with an initial velocity of 60.0 m/s at an angle of 30.0° above the horizontal. How far does it travel? A) 152 m B) 160 m C) 184 m D) 318 m D) 318 m
Solve for me this problems. Please solve 14, 15, 16. Thank you so much. all problems. 14) A large rock falls from the side of a cliff. It falls 8.5 m before striking a car driving at 95 km/hr. From the frame of reference of the car, what is the velocity and angle of impact? 15) A stunt rider needs to clear 24 m with her motorcycle using a launch ramp. The ramp is at an angle of 30 and...
A rock is thrown horizontally from a bridge with a velocity of 10.0 m/s. It takes the rock 2.9 s to strike the water below. What is the magnitude of the velocity of the rock just before it hits the water?
Show work, please. A bullet is fired horizontally at 500 m/s at 1.5 m above the ground. How far does the bullet travel before it hits the ground?
A balloon carrying a basket is descending at a constant velocity of 20.0m/s . A person in the basket throws a stone with an initial velocity of 15.0m/s horizontally perpendicular to the path of the descending balloon, and 9.00s later this person sees the rock strike the ground. a) How high was the balloon when the rock was thrown out? b) How far horizontally does the rock travel before it hits the ground? c)At the instant the rock hits the...
iPad 3:59 PM * 48%. 115:33:08 Exit 1 A rifle is fired straight up, and the bullet leaves the rifle with an initial velocity magnitude of 525 m/s. After 4.15 s, the velocity is 482 m/s. At what rate (in m/s2) is the bullet decelerated? (Recall that a negative sign denotes negative acceleration, or deceleration.) Enter answer 2 A rock thrown straight up climbs for 3.50 s, then falls to the ground. Neglecting air resistance, with what velocity (in m/s)...
Could you please show your work as well? Thank you! A girl is sledding down a slope that is inclined at 28.0 with respect to the horizontal. The wind is aiding the motion by providing a steady force of 110 N that is parallel to the motion of the sled. The combined mass of the girl and the sled is 61.7 kg, and the coefficient of kinetic friction between the snow and the runners of the sled is 0.195. How...
