What is the velocity and  acceleration of the ball at the higest point (peak)?   A. velocity = 0m/s and acceration = 9.8 m/s2 down.   B. velocity = 0 m/s  amd acceleration = 0 m/s2   C. velocity = 0 m/s and acceleration = 9.8 m/s2 up   D. velocity = 9.8 m/s up and acceleration = 0 m/s2

HOW?An automobile travels on straight road for 39km at 24km/h. If then continues in the same direction for another 39 km at 48km/h.  a. What is the average velocity of the car during his 78 km trip? (Assume that it moves positive direction) b. What is the average speed?

2. A jet plane has a takeoff speed of vtakeoff = 73 m/s and can move along the runway at an average acceleration of 2.4 m/s2. The runway is 1.2 km. Write out the 3 Kinetic equations. a. b. Write out the values of initial position, initial velocity, and acceleration. How many seconds will it take for the plane to reach takeoff speed? с. d. How far will the plane have to travel to get to takeoff speed? will the plane be able to get to take off before it gets to the end of the runway? е.

You are driving down a straight road at night in your McLaren MCL34 Formula 1 racecar at an entirely illegal speed of 98 m/s when Bambi and Thumper jump onto the road in front of you. Because you were texting while driving (also illegal), your reaction time is a rather slow; 1.3 seconds before your foot touches the brake. How far did you travel during this time? O a. 98 m O b. 127 m O c. 101 m O d. 134 m O e. 112 m Clear my choice

1. You are driving at 8.00 m/s south. You accelerate uniformly at 1.10 m/s? north for 5.00 seconds. How fast are you going at the end of the 5.00 seconds? What is your displacement?

Page < c. The acceleration is +1.5 m/s². d. The acceleration is +3.0 m/s². e. The acceleration cannot be determined. 2 Multiple Choice Questions 1. A car enters a 25-m intersection travelling with a velocity 5 m/s in the west direction. When it clears the intersection (after it covers the 25-m), it is travelling with a velocity of 10 m/s still in the west direction. What is the acceleration of the car? Assume that east is in the positive x-axis and west is in the negative x-axis. a. The acceleration is -9.81 m/s. b. The acceleration is -1.5 m/s².

A safety measure when driving cars is to leave a separation of "3 s" with respect to the next car. This rule has made it possible to avoid many accidents. a. If a car travels at 60 km / h, what distance (in meters) will it travel in 3 seconds? Assuming there is an accident 20 m from where you are, what acceleration must you have to bring the car to a complete stop before reaching the accident?b. Repeat part a considering a speed of 90 km / hc. Repeat part a considering a speed of 120 km / hd. Repeat part a considering a speed of 150 km / h

1. The cheetah can reach a top speed of 114 km/h. while chasing its prey in a short sprint, a cheetah starts from rests and runs 45 min in a straight line, reaching a final speed of 72 km/h. a. Determine the cheetah's average acceleration during the short sprint, and b. Find its displacement at t= 3.5 s O 4.4m/s2, 27m O 5.6m/s2, 56m O 1.2m/s2, 15m

At the instant the traffic light turns green, a car starts from rest with a constant acceleration of 3.0 m/s2 . At that instant, a truck travelling with a constant speed of 36 km/h overtakes and passes the car. a. How long does it take the car to overtake the truck?  b. How fast will the car be travelling when it overtakes the truck.
