Mass = 1kg
Distance = 1m
Time = 1s
Force= Mass x Acceleration due to graviy
= 1 x 9.8 = 9.8
Velocity = Distance / time
= 1 / 1 =1m/s
Power = Force x velocity
= 9.8 x 1 = 9.8 W
Answer:
a= g sinθ
Explanation:
Given that
Angle ,θ = 15° (from the horizontal)
Lets take the mass of the block = m
The acceleration due to gravity = g
The acceleration of the block = a
When block slide down :
The gravitational force on the block = m g sinθ
By using Newton's second law
F= m a
F=Net force ,a acceleration ,m=mass
m g sinθ = ma
a= g sinθ
Therefore the acceleration of the block will be g sinθ.
Answer:
A
Explanation:
THAT is th equation for Potential Energy
<span>Power = Force * Velocity </span>
<span>First convert to SI units: </span>
<span>88 km/h = 24.44 m/s </span>
<span>18 Hp = 13,428 Watts </span>
<span>Force = P/V = 549 newtons</span>
Answer:
14.29m/s
Explanation:
v1' = ((m1 - m2) / (m1 + m2)) v1
v2' = (2m1 / (m1 + m2)) v1
Where
m1,m2 - Mass of Moving Objects
v1 - Velocity of Moving Objects
