A racing car whose mass is 1.2 X 10^3 kg is travelling at 8.9 m/s. It stops with a constant deceleration in a distance of 1.8X10
Alexeev081 [22]

given that initial speed of the car is

v_i = 8.9 m/s

now after travelling the distance d = 1.8 * 10^1 m the car will stop

so here we can use kinematics to find the acceleration of car

v_f^2 - v_i^2 = 2 a d

0 - 8.9^2 = 2 a d

here we have

- 79.21 = 2*(18)*a

a = -2.2 m/s^2

net force applied due to brakes of car is given by Newton's II law

F = ma

here we have

mass = 1.2 * 10^3 kg

F_{net} = 1.2 * 10^3 * 2.2

F_{net} = 2.64 * 10^3 N

now we can say

F_{net} = F_1 + F_2

2.64 * 10^3 = 1.8 * 10^3 + F_2

F_2 = 8.4 * 10^2 N

So the force applied due to brakes is given as above

Suppose a star the size of our Sun, but of mass 9.0 times as great, were rotating at a speed of 1.0 revolution every 17 days. If

Use the conservation of angular momentum; angular momentum at the beginning = angular momentum at the end 
Conservation of angular momentum: 
I1 w1 = I2 w2 
Where I is the moment of inertia. For a sphere, I=2/5 m R^2. Substituting into the equation above we get 
w2 = I1 w1 / I2 = w1 m1 R1^2 / (m2 R2^2) 
w2 = w1 4 * (R1/R2)^2
= 4*(1)*(7E5/7.5)^2
= 3.48E10 revs/(17days)
= 2.04705882 x 10^9 revs/sec
