Explanation:
K.E. of marble 1 = (1/2) × 0.2 × (22/0.8) ^2
= 0.1 × 756.25
= 75.625
K.E. of marble 2 = (1/2) × 1.2 × (26/0.8)^2
= 0.6 × 1056.25
= 633.75
Answer:
0.52 N
Explanation:
k = 13 N/m
x = 0.04 m
Plug those values into Hooke's Law:
F = kx
F = (13 N/m)(0.04 m)
F = 0.52 N
Answer:
the acceleration of the car is -5 m/s².
Explanation:
Given;
initial velocity of the car, u = 50 m/s
time of motion, t = 6 s
final velocity of the car, v = 20 m/s
The acceleration of the car is calculated as;
Therefore, the acceleration of the car is -5 m/s².
