Drupady [299]

Answer:

7.6427m/s

Explanation:

Given:v_a=4.7m/s, \theta_a=33.0\textdegree and \ v_b=4.5m/s

#Applying the conservation of momentum along the x-axis:mv_i=mv_acos\theta_a+mv_bcos\theta_b

#And along y-axis:

0=-sin\theta_a+mv_bsin\theta_b

#Solving  for \theta_b:

sin\rheta_b=\frac{v_a}{v_b}sin\theta_a=4.7/4.5\times sin33.0\textdegree\\=0.5688\\\therefore \theta_b=34.67\textdegree

#By substitution in the x-axis equation:

v_i=4.7cos 33.0\textdegree +4.5cos 34.67\textdegree\\=7.6427m/s

Hence the original speed of the ball before impact is 7.6427m/s

Sidana [21]

Answer:

a=8.1832m/s^2

Explanation:

Vo=initial speed=0m/s

Vf=final speed=26.8m/s

t=time=3.275s

the vehicle moves with a constant acceleration therefore we can use the following equation

A=aceleration=(Vf-Vi)/t

A=(26.8m/s-0m/s)/3.275s=8.1832m/s^2

the magnitude of the car´s aceleration is 8.1832m/s^2
