15 minutes = 15*60 = 900 seconds
900x1.1 = 990 m
Answer:
Explanation:
The problem is based on conservation of angular momentum.
Moment of inertia of the disc = 1/2 m R² , m is mass of the disc and R is its radius.
= 1/2 x 98.1 x 1.51²
= 111.84 kg m²
Moment of inertia of disc + moment of inertia of bananas + monkey
= 1/2 x 98.1 x 1.51² + 9.29 x .45 x 1.51 + 20.3 x 1.51² ( moment of inertia of banana and monkey will be equal to mass x radial distance from axis² )
= 111.84 + 6.31 +46.28
= 164.43 kg m²
Now applying law of conservation of angular momentum
= I₁ ω₁ = I₂ω₂
111.84 x 1.69 = 164.43 x ω₂
ω₂ = 1.15 rad / s
Answer:
e) 31.6 seconds
Explanation:
t = Time taken
u = Initial velocity
v = Final velocity
s = Displacement
a = Acceleration
Equation of motion




Time taken by the cars to meet 31.6 seconds.
Answer:
The force of the ball on the bat is same as the force of the bat on the ball.
Explanation:
A bat hits the ball and the ball moves to the out filed.
According to the Newton's third law, for every action there is an equal and opposite reaction.
The action and the reaction forces acts on the two different bodies but the magnitude of the force is same.
As the ball is hitted by the bat, the bat exerts the force on the ball and the same force is exerted on the bat by the ball according to the Newton's third law.
So, the force of the ball on the bat is same as the force of the bat on the ball but the direction of force is opposite.
