Answer:
the velocity of car when it passes the truck is u = 16.33 m/s
Explanation:
given,
constant speed of truck  = 28 m/s
acceleration of car = 1.2 m/s²
passes the truck in 545 m 
speed of the car when it just pass the truck = ?
time taken by the truck to travel 545 m
               time = 
 
               time = 
 
               time =19.46 s
velocity of the car when it crosses the truck


u = 16.33 m/s
the velocity of car when it passes the truck is u = 16.33 m/s

Answer:

Explanation:
The relationship between the linear distance covered by an object and its angular displacement is given by the following formula:
s = rθ
where,
s = distance traveled on road = ?
r  radius of tires = diameter/2 = 2.2 m/2 = 1.1 m
θ = angular displacement = (60 rev)(2π rad/1 rev) = 377 rad
Therefore,

 
        
             
        
        
        
This is a power problem which requires the rearranging of a formula. The lamps energy used is 5 N, and the TV’s usage is 116.7 N (rounded from 116.6666repeating). Here my work:
