Answer:
The time spent in air by the car is 2.19 s
The height of the cliff is 58.5 m
Explanation:
Given;
initial velocity of the car, u = 16 m/s
horizontal distance traveled, R = 35 m
The horizontal distance or range of a projectile is given as;
R = vt
where;
t is the time spent in air by the projectile
t = R/v
t = 35 / 16
t = 2.19 s
The height of the cliff is given as;
h = ut + ¹/₂gt²
h = (16 x 2.19) + ¹/₂(9.8)(2.19)²
h = 58.5 m
Stay away from water. Try not to wash, shower, wash dishes, or have some other contact with water during a thunderstorm because lightning can travel through a building's plumbing.
Further Explanation:
Be aware
Check the climate conjecture before taking an interest in outside exercises. In the event that the estimate calls for tempests, defer your excursion or movement, or ensure sufficient safe house is promptly accessible.
Go inside
Keep in mind the expression, "When thunder thunders, go inside." Find a protected, encased asylum when you hear thunder. Safe havens incorporate homes, workplaces, strip malls, and hard-top vehicles with the windows moved up.
Hunch near the ground and isolated
On the off chance that you are gotten in an open zone, hunker down in a ball-like position (feet and knees together) with your head tucked and hands over your ears so you are down low with insignificant contact with the ground. Try not to rests. Lightning causes electric flows along the highest point of the ground that can be fatal more than 100 feet away. Hunching down is the best mix of being low and contacting the ground as meager as could be expected under the circumstances.

On the off chance that you are in a gathering during a rainstorm, separate from one another. This will decrease the quantity of wounds if lightning strikes the

Answer:
vx = 65 yd/3 sec = 21.7 yd/sec since horizontal speed is constant
vy = g t = (32 / 3) yd/sec^2 * 1.5 sec = 16 yd/sec where 32/3 is the acceleration due to gravity in yds / sec^2 and 1.5 is the time to travel each way in the vertical direction
V = (vx^2 + vy^2)^1/2 = (21.7^2 + 16^2)^1/2 = 27 yd/sec
tan theta = vy/vx = 16 / 21.7 = .737 theta = 36.4 deg
You can check using the range formula:
R = v^2 sin (2 theta) / g = 27^2 * .955 / (32 / 3) = 65.3 yds
The difference from 65 yds may be rounding error.
