Physics
A motorcycle is following a car that is traveling at constant speed on a straight highway. Initially, the car and the motorcycle are both traveling at the same speed of 19.0 m/s , and the distance between them is 52.0 m . After t1 = 3.00 s , the motorcycle starts to accelerate at a rate of 4.00 m/s^2. The motorcycle catches up with the car at some time t2.
Required:
a. How long does it take from the moment when the motorcycle starts to accelerate until it catches up with the car?
b. How far does the motorcycle travel from the moment it starts to accelerate (at time t1) until it catches up with the car (at time t2)?

Ответ:
length=10 width =5 Perimeter =30
Step-by-step explanation:
Area =LxW
If area is 50cm^2 and length is 5cm more than The width then the length must be 10cm. Now divide the area by the length to get width. 50/10=5 which is the width.
The formula for perimeter is P=2L+2W
P=2(10)+2(5)
P=30
