Answer:
The acceleration and time are 588 m/s² and 0.071 sec respectively.
Explanation:
Given that,
Speed = 42.0 m/s
Distance = 1.50 m
(a). We need to calculate the acceleration
Using equation of motion
Put the value in the equation
(b). We need to calculate the time
Using equation of motion
Hence, The acceleration and time are 588 m/s² and 0.071 sec respectively.
Newton's third law: For every action, there is an opposite and equal reaction.
Answer:
acceleration, a = 9.8 m/s²
Explanation:
'A ball is dropped from the top of a building' indicates that the initial velocity of the ball is zero.
u = 0 m/s
After 2 seconds, velocity of the ball is 19.6 m/s.
t = 2s, v = 19.6 m/s
Using
v = u + at
19.6 = 0 + 2a
a = 9.8 m/s²
Tornado
Tornadoes are narrow, funnel-shaped spirals of rapidly rotating air that form in association with thunderstorms. And they are also near-circular low pressure systems.
Since distance is a scalar and not a vector, the total distance traveled is the sum of all the distances covered throughout the journey.
In Physics, we have two categories of quantities;
The difference between vectors and scalars is that vectors has direction but scalars do not have direction. Both quantities posses magnitude.
The total distance covered can be obtained algebraically since distance is a scalar.
Hence, total distance covered = 2 cm + 6cm + 5 cm = 13 cm
