Answer:
a) 456.48m
b) 3343.91m
c) - 76.376m
Total displacement = 3724.01m
Explanation:
Using kinematic equation for displacement
◇x1 = Vo t + 1/2 at^2
Where ◇x1 = displacement
Vo = initial velocity
a = acceleration
t = time
◇x1 = 0(15.3) + 1/2 (3.9)(15.3)^2
◇x1 = 0 + 456.48
Displacement = 456.48m
b) ◇x2 = Vt1
V = velocity = 59.67m/s
◇x2 = 59.67 ×0.934minute×60seconds
◇x2 = 59.67 ×56.04 = 3343.91
c)
a= -11.1m/s
= (-11.1 m/s^2× 3.71seconds)
◇ x3 =1/2 (41.18m/s ×3.71)
◇x3 =- 76.376m
Total displacement = ◇x1 + ◇x2 + ◇x3
Total displacement = 456.48 + 3343.91 - 76.376
Total displacement = 3724.01m
U=mgh
U=10*9.8*20
U=1960
Answer is D
Answer:
Around 3.57m/s
Explanation:
p=mv
Let's denote the momentum, mass, and velocity of the car with the subscript 1, and for the truck use 2. After the collision, the combined momentum can be denoted with the subscript 3.
