Find the magnitude, in meters per second, of ball’s initial velocity.

A truck travels due east for a distance of 1.2 km, turns around and goes due west for 7.2 km, and finally turns around again and travels 2.6 km due east.(a) What is the total distance (in km) that the truck travels? (Enter a number.)______km(b) What are the magnitude (in km) and direction of the truck's displacement? (Enter a number.)magnitude_______kmdirection (a)east (b)west    (c)neither

A baseball is hit almost straight up into the air with a speed of 24 m/s . Estimate how long it is in the air. Express your answer to three significant figures and include the appropriate units.

Ex. 2. A car driver in northern Ontario makes the following displacements: Ad₁= 15.0 km [W 30.0°N] Ad2 = 10.0 km [W 75.0°N] Ad3= 10.0 km [E 70.0° N] The trip takes 0.50 h. Calculate the average velocity of the car and driver in km/h.

A ball is thrown from a rooftop with an initial downward velocity of magnitude vo = 4.2 m/s. The rooftop is a distance above the ground, h = 21 m. In this problem use a coordinate system in which upwards is positive.     Part (a) Find the vertical component of the velocity, vfy, in meters per second, with which the ball hits the ground. Numeric   : A numeric value is expected and not an expression.vfy = __________________________________________Part (b) If we wanted the ball's final speed to be exactly 27.3 m/s, from what height, hnew (in meters), would we need to throw it with the same initial velocity?Numeric   : A numeric value is expected and not an expression.hnew = __________________________________________Part (c) If the height is fixed at 21 m, but we wanted the ball's final speed to be 32.7 m/s, what would the vertical component of the initial velocity viy need to be, in meters per second?Numeric   : A numeric value is expected and not an expression.viy =…

A car is traveling east at 17.5 m/s when it turns due north and accelerates to 32.5 m/s, all during a time of 5.00 s. Calculate the magnitude of the car's average acceleration (in m/s2).

An insect takes 8.03 minutes to walk 19.9 m toward the south along a deserted highway. A driver stops and picks up the insect. The driver takes the insect to a town 1.62 km to the north with an average speed of 15.6 m/s. What is the magnitude of the average velocity of the insect for its entire journey? Express your answer to 3 significant figures in meters/second.

An object's position as a function of time in one dimension is given by the expression; 3.89t2 + 2.22t + 7.48 where are constants have proper SI Units. What is the object's average velocity between the times t = 3.16 s and t = 8.38 s? Quantities and answer in 3 sig figs

The vertical displacement (in m) of a plane is  1.5 t2 up; t is the time (in s) after takeoff. The plane releases a package 2.0 s after takeoff. What is the magnitude of the velocity (in m/s) when the packaged is released? Report your answer in the appropriate number of significant digits. Answer value
