The average speed is 52km
Answer with Explanation:
We are given that
Constant speed of Jane=12.6 m/s
a.When Fred can throw the ball 30 m/s
We have to find the angle relative to the horizontal when he throw the ball in order for Sue to see the ball travel vertically upward.

be the angle .
Therefore,



b.We have to find the height to which ball reach.



<h2>
Answer: 1.252</h2>
Explanation:
We are given this equation and we need to find the value of
:
(1)
Firstly, we have to clear
:
(2)
Applying<u> Natural Logarithm</u> on both sides of the equation (2):
(3)
(4)
According to the Natural Logarithm rules
, so (4) can be written as:
(5)
Finally:
Answer:
a= 0.5m/s^2
Explanation:
Force applied on an object is known as
F=m.a (Newton's second law states it)
a=F/m
a=5/10=0.5m/s^2
