A ball is thrown straight upward, and it reaches a maximum height of 2.80 seconds.   b). What is the maximum height reached by the ball shown in a formula showing what the variables are defined as in a diagram?

Please help me in a step by step solution for problem #10?

Pls help ASAP

3. A tennis ball is thrown up in the air. It's height is given by h(t) = -5t2 + 23t + 2, where h(t) is in meters and t is in seconds. Use technology to answer: a.) What is the max height of the tennis ball? When does it occur? b.) How long was the tennis ball in the air?

A bus makes a trip according to the position-time graph shown in the drawing. What is the average velocity (magnitude and direction) of the bus during each of the segments A, B, and C? Express your answers in km/h. The scale for the time axis is 2 h per increment, and scale for the velocity axis is 210 km per increment. (Indicate direction by the sign of the velocity.) segment A segment B segment C km/h km/h km/h Show My Work (Optionall Time (h)

When a 0.0577-kg golf ball takes off after being hit, its speed is 42.6 m/s. (a) How much work is done on the ball by the club? (b) Assume that the force of the golf club acts parallel to the motion of the ball and that the club is in contact with the ball for a distance of 0.0231 m. Ignore the weight of the ball and determine the average force applied to the ball by the club. (a) Number i Units (b) Number i I Units

A cat walks in a straight line, which we shall call the -axis, with the positive direction to the right. As an observant physicist, you make measurements of this cat's motion and construct a graph of the feline's velocity as a function of time (Figure 1). I. Calculate the area under the graph between t = 0 and t = 6.0 s. (Express your answer to two significant figures and include the appropriate units.) II. For the time interval t = 0 to t = 6.0 s, what is the magnitude of the average velocity of the cat? (Express your answer to two significant figures and include the appropriate units.) III. Use constant-acceleration equations to calculate the distance the cat travels in this time interval. (Express your answer to two significant figures and include the appropriate units.)

How many significant figures does each of the following numbers have?a. 6.21                 b. 62.1c. 0.620               d. 0.062
