Yes what do you need help on
You’re right, bc I’m the question it says the pulley is at equilibrium
Answer:
a=-4.2 m/s²
Explanation:
The horse riding so inital velocity is given finally the rider stops so the final velocity is zero.
initial velocity =Vi= 21 m/s
final velocity =Vf= 0 m/s
distance covered = S=52 m
By using 2nd equation of motion we can find the acceleration
2aS=Vf² -Vi²
a=(-441)/104
a=-4.2 m/s²
So the accceleration is 4.2 m/s².
A) 6m cause it is at its highest speed
B)9.81*cos(36.87)+6*sin36.87)
C)6m/s
