How much kinetic energy does a 4.50kg block with a speed of 5.00m/s have?
1 answer:
Answer:
56.25J
Explanation:
Kinetic energy = 1/2 mv^2
Where m = mass
v = velocity
Given m = 4.50kg
v = 5.00m/s
Kinetic energy = 1/2 x 4.50 x (5.00)^2
= 1/2 x 4.50 x (5.00 x 5.00)
= 1/2 x 4.50 x 25
Multiply through
= 112.5/2
= 56.25J

Answer:
(a) x0 = 0m and y0 = 49.0m
(b) Vox = 15.0m/s Voy = 0m/s
(c) Vx = Vo = 15.0m/s and Vy = -gt
(d) X = 15.0t and y = 49.0 - 4.9t²
(e) t = 3.16s
(f) Vf = 34.4m/s
Explanation:
Using Newton's Second Law, we can find the air resistance. We know the net force is equal to mass times acceleration.
