Answer:
θ = 13.16 °
Explanation:
Lets take mass of child = m
Initial velocity ,u= 1.1 m/s
Final velocity ,v=3.7 m/s
d= 22.5 m
The force due to gravity along the incline plane = m g sinθ
The friction force = (m g)/5
Now from work power energy
We know that
work done by all forces = change in kinetic energy
( m g sinθ - (m g)/5 ) d = 1/2 m v² - 1/2 m u²
(2 g sinθ - ( 2 g)/5 ) d = v² - u²
take g = 10 m/s²
(20 sinθ - ( 20)/5 ) 22.5 = 3.7² - 1.1²
20 sinθ - 4 =12.48/22.5
θ = 13.16 °
Answer:
I just want the points but you should pay attention in class jk
We can feel it as heat, using the nerve endings in our skins.
Answer:
Time, t = 0.57 hours
Explanation:
It is given that,
Speed of the school bus, v = 35 mi/hr
Distance covered by the bus, d = 20 miles
We need to find the time taken by the bus to get to school. Time taken by the bus is given by :
t = 0.57 hours
So, the time taken by the bus to reach school is 0.57 hours. Hence, this is the required solution.
