Answer:
Angle is 55.52°
and Initial Speed is v=26.48 m/s
Explanation:
Given data

Applying the kinematics equations for motion with uniform acceleration in x and y direction
So

Put the value of v₀ from equation (1) to equation (2)
So

Put that angle in equation (1) or equation (2) to find the initial velocity
So from equation (1)

Answer:
The minimum distance in which the car will stop is
x=167.38m
Explanation:

∑F=m*a
∑F=u*m*g
The force of friction is the same value but in different direction of the force moving the car so it can stop so



Answer:
Associations Clusters
Explanation:
There is three basic type of clusters, globular clusters, open clusters, associations clusters. Associations cluster consist of younger stars that is younger than globular and open clusters stars.
It’s c because it’s not Control so that means that it would be broken and non fix able
