Explanation:
It is given that,
The angle of projection is 60 degrees
Initial velocity of the ball is 120 m/s
We need to find the time taken to get to the maximum height and the time of flight.
Time taken to reach the maximum height is given by :
g is acceleration due to gravity
(ii) Time of flight,
So,
Hence, this is the required solution.
As the greater force of tension (by 81N) is exerted by the team on the right the rope will move to the right.
Answer:
Pls mark me brainliest
Explanation:
The wheel and axle is a simple machine consisting of a wheel attached to a smaller axle so that these two parts rotate together in which a force is transferred from one to the other.
F=ma
a=(v2-v1)/(t2-t1)
a=(6-0)/(12-0)
a=6/12
a= .5 m/s^2
f=2300kg*.5m/s^2
f=1150N
f=1200N if using correct sig figs
Is there any chemical names listed ?
