Since the motor cycle was moving at 36 m/s before the brakes were applied, the initial velocity
The motorcycle traveled 23m before stopping, that means
Since the motorcycle stopped moving the final velocity is zero.
We can use this 'suvat' equation of linear motion.
Plugging in the above values gives,
We can use the equation
to find the time the motorcycle took to stop.

Answer:
The maximum range m
Explanation:
Given,
The initial velocity of the car, u = 30 m/s
The height of the cliff, h = 50 m
Let the car drives off the cliff with a horizontal velocity of 30 m/s.
The formula for a projectile that is projected from a height h from the ground is given by the relation
m
Where,
g - acceleration due to gravity
Substituting the values in the above equation
= 132.72 m
Hence, the car lands at a distance, m
