The eastern time zone would the opposite side of the angle made by his car. So this means he would be traveling 30cos30 m/s completely in the east direction. Or approximately 26 m/s in the East direction. 5000 m divided by this answer results in approximately 192 seconds. I would use a calculator to get a more exact answer
Answer:
25.2 cm
Explanation:
K = 1050 N/m
m = 1.95 kg
h = 1.75 m
By the conservation of energy, the potential energy of the block is converted into the potential energy stored in the spring
m g h = 1/2 x k x y^2
Where, y be the distance by which the spring is compressed.
1.95 x 9.8 x 1.75 = 1/2 x 1050 x y^2
33.44 = 525 x y^2
y = 0.252 m
y = 25.2 cm
Answer:
Impulse of force = 300Ns
Explanation:
Given the following data;
Mass = 25kg
Change in velocity = 12m/s
To find the impulse;
Impulse is given by the formula;
Substituting into the equation, we have;

Impulse of force = 300Ns
