Answer:
if i do give me brainliest ok ok
Explanation:
The radius of the curve is 81.93 metres. We can work this out by
considering the centripetal force (Fc) = mass x centripetal
acceleration.
Fc = m x u (squared)
R = mu (squared) over Fc = 1600 x (13 squared) over 3300
R = 81.93 metres
I know that 1 is more gas but the others I cant read them.

Here's the answer:
Explanation:
An average open-water certified diver using a standard aluminium 80-cubic-foot tank on a 40-foot dive will be able to stay down for about 45 to 60 minutes before surfacing with a safe reserve of air still in the tank.
Three Factors That Determine How Long a Diver's Air Will Last:
1. Tank Volume
2. Depth
3. Air Consumption Rate
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
