Answer:
Part a)
Angle in degree is given as
Part b)
Size of the object is
Explanation:
Part a)
As we know that
180 degree = radian
so we have
so we have
Part b)
As we know that the relation of angle with radius is
Answer:
Playing hockey, driving a car, and even simply taking a walk are all everyday examples of Newton's laws of motion.
Answer:
Explanation:
Mass of station wagon M = 1200 kg , velocity V = 12 m/s
Mass of car m = 1800 kg , velocity v = 20 m/s
a ) Let centre of mass of car and station wagon be at a distance d from wagon
Taking moment of weight about it
1200 x d = 1800 x ( 40 - d )
3000 x d = 1800 x 40
d = 24 m
b ) Total momentum = MV +mv
= 1200 x 12 + 1800 x 20
= 50400 kg ms⁻¹
c ) Speed of centre of mass
v₀ = (MV + mv )/(m+M)
= 50400/3000
= 16.8 m/s
d) System Total momentum = velocity of cm x total mass
= 16.8 x 3000 = 50400 m/s .
It is equal to what was calculated in part b)
The runner's acceleration during this time interval is 10
<u>Given the following data:</u>
- Initial velocity, U = 0 m/s (since the sprinter is starting from rest).
- Final velocity, V = 10.0 m/s
To calculate the runner's acceleration during this time interval, we would use the first equation of motion;
Mathematically, the first equation of motion is calculated by using the formula;
<u>Where:</u>
- U is the initial velocity.
- t is the time measured in seconds.
Substituting the given parameters into the formula, we have;
Therefore, the runner's acceleration during this time interval is 10
