Velocity of an object is given as
now we have
time = 3 hours
now from above formula
so its velocity is 40 mph and its a vector quantity whose direction is towards NORTH
correct answer is B
Answer:
Momentum
Explanation:
Truck A has a greater momentum compared to Truck B.
Momentum is the product of mass and velocity of a body;
Momentum = mass x velocity
We see that the body with more mass and velocity will have a higher momentum.
Since the two bodies have the same mass, and the speed A is greater, then A will have a greater momentum.
Answer:
<em>t = 1.02 s</em>
Explanation:
friction = 0 N (no slipping)
downward force along the inclined plane = F = mgsin(30.8)
F = ma
⇒ a = 9.81 sin(30.8)
a = 5.02 m/s^2
now we have
displacement = s = 2.6 m
acceleration = a = 5.02m/s^2
initial velocity = Vi = 0m/s
time = t = ?
<u>APPLYING THE 2ND EQUATION OF MOTION:</u>
<em> S = (Vi)(t)+0.5at^2</em>
<em>2.6 = 0(t) + 0.5 * 5.02 * t^2</em>
<em>t = 1.02 s</em>
According to the USDA, 40% of our food worth $161 billion is not even harvested, lost in processing, thrown away in restaurants and homes or ended up rotting in America’s landfills. It is also reported that 50% of the produce is never consumed.
Disparities in food distribution and availability imply that numerous communities and neighborhoods have very constrained access to fresh affordable food. Also, a significant number of those with a bounty of food choose to toss it rather than donate it.
Another type of food waste comes from produce discarded by millions of backyard cultivators due to their gardens producing far more fruits and vegetables than they might use, preserve or give to friends and neighbours.
Answer:
Centripetal acceleration of the car is 17.4 m/s²
Explanation:
It is given that,
Radius of the track, r = 57 m
Speed of car, v = 31.5 m/s
We need to find the centripetal acceleration of the race car. The formula for the centripetal acceleration is given by :
So, the centripetal acceleration of the race car is 17.4 m/s². Hence, this is the required solution.
