I):final velocity=initial velocity+acceleration due to gravity*time of travel
Therefore,
v=0+9.8*3.1
=30.38 m/s

Answer:
0.775 m
Explanation:
As the car collides with the bumper, all the kinetic energy of the car (K) is converted into elastic potential energy of the bumper (U):
![U=K\\frac{1}{2}kx^2 = \frac{1}{2}mv^2](https://tex.z-dn.net/?f=U%3DK%5C%5Cfrac%7B1%7D%7B2%7Dkx%5E2%20%3D%20%5Cfrac%7B1%7D%7B2%7Dmv%5E2)
where we have
is the spring constant of the bumper
x is the maximum compression of the bumper
is the mass of the car
is the speed of the car
Solving for x, we find the maximum compression of the spring:
![x=\sqrt{\frac{mv^2}{k}}=\sqrt{\frac{(30\cdot 10^4 kg)(2.0 m/s)^2}{2\cdot 10^6 N/m}}=0.775 m](https://tex.z-dn.net/?f=x%3D%5Csqrt%7B%5Cfrac%7Bmv%5E2%7D%7Bk%7D%7D%3D%5Csqrt%7B%5Cfrac%7B%2830%5Ccdot%2010%5E4%20kg%29%282.0%20m%2Fs%29%5E2%7D%7B2%5Ccdot%2010%5E6%20N%2Fm%7D%7D%3D0.775%20m)
Answer:
Vx = 10.9 m/s , Vy = 15.6 m/s
Explanation:
Given velocity V= 19 m/s
the angle 35 ° is taken from Y-axis so the angle with x-axis will be 90°-35° = 55°
θ = 55°
to Find Vx = ? and Vy= ?
Vx = V cos θ
Vx = 19 m/s × cos 55°
Vx = 10.9 m/s
Vx = V sin θ
Vy = 19 m/s × sin 55°
Vy = 15.6 m/s
