Answer:
180 m
Explanation:
Given:
Uniform speed of the car, U = 30 m/s
Uniform acceleration of the motorcycle = 10 m/s²
For the motorcycle to catch up with the car, the distance traveled must be the same.
For the car;
Distance = Speed × Time
⇒ d = u × t
d = 30 × t
d = 30t ......(1)
For the motorcycle;
The stationary police motorcycle has initial speed, u = 0
From equation of motion;
but u = 0
.....(2)
Equating equation (1) and (2)
30t = 5t²
t = 6 seconds
Substituting t = 6 s into equation (2)
d = 5(6)²
d = 5 × 36
d = 180 m
The motorcycle must travel 180 m before it catches up to the car
Complete Question
What is the minimum angular velocity (in rpm) for swinging a bucket of water in a vertical circle without spilling any? The distance from the handle to the bottom of the bucket is 35 cm. The student has 70-cm-long arms
Answer:
The value is
Explanation:
From the question we are told
The distance from the handle to the bottom of the bucket is
The length of the students arm is L = 70 cm = 0.70 m
Generally the acceleration due to gravity experienced by the bucket of water is mathematically represented as
Here is is the radius of the circle which swinging of the bucket makes and this is mathematically represented as
So
= >
= >
= >
Generally the angular speed in revolution per minute is mathematically represented as
