Calculate the speed of the ball, vo in m/s, just after the launch. A bowling ball of mass m = 1.5 kg is launched from a spring compressed by a distance d = 0.21 m at an angle of θ = 32° measured from the horizontal. It is observed that the ball reaches a maximum height of h = 4.4 m, measured from the initial position of the ball. Let the gravitational potential energy be zero at the initial height of the bowling ball.
Ideally, when a thermometer is used to measure the temperature of an object, the temperature of the object itself should not change. However, if a significant amount of heat flows from the object to the thermometer, the temperature will change. A thermometer has a mass of 33.0 g, a specific heat capacity of c = 804 J/(kg C°), and a temperature of 15.4 °C. It is immersed in 149 g of water, and the final temperature of the water and thermometer is 56.0 °C. What was the temperature of the water in degrees Celsius before the insertion of the thermometer?

Korey is planning to open a comic book store. In his first year of operation, Korey expects to average $1,000 of profit each month. He then expects profits to increase by 6% each year for the next 4 years. How much does Korey expect to make in profits in his fifth year of operation?

Answers

First year profit: $1000*12 = $12,000
Second year profit: $12,000 * 1.06
Third year profit: $12,000 * 1.06^2
Fourth year profit: $12,000 * 1.06^3
Fith year profit: $12,000 * 1.06^4 =$15,149.72
:

In this exercise we have to use the knowledge of finance to calculate the  profits that Korey expect to make is $15,149.72.

So organizing the information given in the statement we find that:

  • average $1,000 of profit
  • 6% each year for the next 4 years

Doing these calculations we find that:

1000*12 = $12,000\n12,000 * 1.06^1\n12,000 * 1.06^2\n12,000 * 1.06^3\n12,000 * 1.06^4 =$15,149.72

Is it possible to get a body accelerated even if it is moving with uniform speed? justify.​

Answers

Answer:Yes, A body can have constant speed but still accelerate as in case of uniform circular motion. In uniform circular motion speed remains constant and direction of velocity changes with every point in the direction of tangent drawn from that point.
