Braking a car - Will mark the brainliest
When a car of mass 1000kg is travelling along a level road at a steady speed of 20ms −1
its engine is working at 18kW.
Part D: By how much does this change if the car is travelling down the same hill at 20ms −1
Resistive force = 900N
Brake force = 3100N
Mass of car = 1000kg
initial car speed = 20ms-1
Angle of incline sin theta = 1/20 = 0.05
Magnitude of gravitional field strength = 9.81

The particle p starts from rest at point a at time t = 0 and changes its speed thereafter at a constant rate of 2.8g as it follows the horizontal path shown. determine the magnitude and direction of its total acceleration (a) just before point b, (b) just after point b, and (c) as it passes point c. state your directions relative to the x-axis shown (ccw positive) and choose the angle with the smallest magnitude.
