The acceleration due to gravity on the surface of Mars is reported as 3.7 m/s2. Express this value in terms of km/min2

A car is traveling at a speed of 29 m/s on an interstate highway where the speed limit is 76 mi/h. Is the driver exceeding the speed limit? What is the car's speed in mi/h? Observe correct number of significant figures in your final answer.

A person runs at a pace of 6.52mi/hr. How long does it take the person to run a 15.0⁢km race? (1mi=1.61km)

The distance from the Earth to the moon is 239,000 miles. The distance from the Earth to the moon is 385000 km. Given that light travels at 3.00 × 10⁸ m/s how many minutes does it take for light to travel to the moon?

The time it takes a car to travel from City A to City B is measured as 51 min ± 8 min.  The time it takes the car to travel from City B to City C is measured as 47 min ± 6 min.  What is the total measured time for the car to travel from City A through City B to City C?

For a particle, acceleration is given: a = 4x, units are ft/s^2 and feet. If v = 1.5 ft/s when x = 0, what is v when x = 5ft?

A boxer's fist and glove have a mass of m = 1.04 kg. The boxer's fist can obtain a speed of v = 9.25 m/s in a time of t = 0.21 s. Write a symbolic expression for the magnitude of the average acceleration, aave, of the boxer's fist, in terms of the variables provided.  Find the magnitude of the average acceleration, aave, in meters per square second. Write an expression for the magnitude of the average net force, Fb, that the boxer must apply to his fist to achieve the given velocity. (Write the expression in terms of m, v and t.) What is the numerical value of Fb, in newtons?

A space probe on the surface of Mars sends a radio signal back to the Earth, a distance of 7.96 ✕ 107 km. Radio waves travel at the speed of light (3.00 ✕ 108 m/s). How many seconds does it take for the signal to reach the Earth?

The equation r(t) = ( sin t)i + ( cos t)j + (t) k is the position of a particle in space at time t. Find the particle's velocity and acceleration vectors. π Then write the particle's velocity at t= as a product of its speed and direction. The velocity vector is v(t) = (i+j+ k.

To visit your friend, you first drive on a highway at 55 mi/h for 1.6 hours and then drive on a local road at 20 mi/h for 0.7 hours. What is the average velocity of your trip in mi/h to your friend's home? Your Answer: Answer
