Question

select the correct answer. sully is riding a snowmobile on a flat, snow - covered surface with a constant velocity of 10 meters/second. the total mass of the snowmobile, including sully, is 280 kilograms. if sully accelerates to a velocity of 16 meters/second over 10 seconds, whats the force exerted by the snowmobile to accelerate? use f = ma, where a = \\(\frac{v - u}{t}\\). a. 150 n b. 168 n c. 248 n d. 280 n e. 324 n

Explanation:

Step1: Calculate acceleration

$a=\frac{v_f - v_i}{t}=\frac{16-10}{10}=0.6\ \text{m/s}^2$

Step2: Calculate force

$F=ma=280\times0.6=168\ \text{N}$

Answer:

B. 168 N
