Zero Launch Angle - Car Drives Off a Cliff A car drives straight off the edge of a cliff that is h =40 m high. The police at the scene of the accident note that the point of impact is d =86 m from the base of the cliff. Here the initial speed v0 is unknown. Ignore air resistance. The magnitude of the gravitational acceleration is 9.8 m/s2. Choose the RIGHT as positive x-direction. Choose UPWARD as positive y-direction.
A. In this problem, even though the initial speed v0 is unknown, you can still find v0y, the y component of the initial velocity. What is v0y (in m/s) ?
B.How long (in seconds) is the car in the air before hitting the ground?
C. How fast (in m/s) was the car traveling when it leaves the cliff?
D. What is the vertical component of the velocity (in m/s) just before the car hits the ground? Pay attention to the direction (the sign).
E. What is the magnitude of the velocity (in m/s) (including both the horizontal and vertical components) of the car just before it hits the ground?
F. What is the direction of the velocity of the car just before it hits the ground?
Report the direction by an angle COUNTERCLOCKWISE from the +x axis.
G. Assume the car’s new speed leaving the cliff is 66.0 mph but the height of the cliff is unchanged, still 40 m.
H. What is the new speed in m/s? 1mile = 1609 m, 1 hour = 60 minutes, 1 minute = 60 seconds
m/s
I. what is the time interval (in seconds) from the car leaving the cliff to it hitting the ground?
J.What would be the horizontal distance d (in meters) from the base of the cliff to the impact point?

5) A car drives off a cliff with a horizontal velocity of 20 m/s and a vertical velocity of 3 m/s as shown. It takes 3.5 seconds to hit the ground. How high is the cliff? How far from the edge of the cliff will the car land? him, or past him? (Neglect the guy's height.) a. b. Will it hit the guy, land in front of Use g = 10 m/s2. 3 m/s 20 m's 60 m
A projectile is shot from the edge of a cliff 115 m above ground level with an initial speed of v0 = 56 m/s at an angle of 35.0∘ with the horizontal, as shown in the figure A-Determine the time taken by the projectile to hit point P at ground level. B-Determine the distance X of point P from the base of the vertical cliff. C-At the instant just before the projectile hits point P, find the horizontal and the...
A child standing at the top edge of a 21.0-m high cliff kicks a soccer ball. The ball’s initial velocity is 13.1 m/s, in a direction 31.2° above the horizontal. Ignore drag for this problem. Provide all answers to 3 SF. (a) State your choices for the speed and direction of the initial velocity, and use them to calculate the horizontal and vertical components of the ball's initial velocity. (b) Calculate the vertical component of the ball's velocity just as...
A car drives straight off of a horizontal cliff with a speed of 54.9 m/s. If it is in the air for 4.01 s, how far from the base of the cliff does the car land? And what is the height of the cliff? X= | Number | | Units Y= | Number | | Units
A hiker throws a stone from the upper edge of a vertical cliff. The stone's initial velocity is 25.0 m/s directed at 40.0° with the face of the cliff, as shown in the figure. The stone hits the ground 3.75s after being thrown and feels no appreciable air resistance as it falls. (a) What is the height of the cliff (b) How far from the foot of the cliff does the stone land? (c) How fast is the stone moving...
A rock is thrown horizontally with a speed of 20 m/s from a vertical cliff of height 25 m. What is the velocity (magnitude and direction counterclockwise from the +x-axis, which is the initial horizontal direction in which the rock was thrown) of the rock just before it hits the ground? Magnitude - Direction - degrees
